I can't make an executable because this game uses a different engine, but I could probably have an html file available for download.  I'd like to iron out more of the unintended solutions before doing that though, so I'll let you know when I do!

Thanks!  It seems I had forgotten to add Puzzlescript as the engine, hopefully it shows up properly now.

Make sure both blocks you are using to make the square block are sticky.  You can put a downward block on top of one and a rightward block on top of the other and the diagonal will be formed directly on top of the square block when the pistons trigger.  The extra setup is moving the rightward block over to one of the pistons before getting onto the platform with the blocks.  The third piston is for making the second diagonal, which happens after dropping back down from the platform.

I'm not super happy with how the puzzle turned out.  I missed a lot of moves (mostly alternate ways to form the diagonals) and it ended up being more difficult and frustrating than intended, though I do know of two people who have solved the latest version without help.

It sounds like you are making the square block correctly (those restrictions are all planned) but you may be stuck unless you already have a diagonal made.  You can make the first diagonal at the same time as the square block.  You shouldn't need to change the way you make the square block much, it just requires some extra setup.  Let me know if you want more details.

The timing for this part is tricky, hopefully this explanation helps (also, just to confirm, you won't need to drop more than two downward blocks to the ground and you won't ever need to raise blocks off of the ground again after you get onto the platform with the blocks).   The paths to each button from the diagonal don't need the same number of pieces, as you can essentially speed up a path by having another stationary block sitting along it.  As an example, suppose a block is sitting two spaces away from a diagonal and you push a new block onto that diagonal. After the first time step, the block is one space away from the diagonal.  On the second time step, it pushes the stationary block onto the tile three spaces away from the diagonal, so you get an object three spaces along the path in only two time steps.  You can use this trick to synchronize the button presses even if the paths aren't equal length.

I don't know the specifics of your previous solution, but my guess is the way you made the diagonals probably won't work anymore.  Regarding making the square block, using the diagonal is correct and using the risers on the right to elevate yourself is also correct.

The diagonals are still going to be made on the upper level if that is what you are referring to, but if you were using additional downward blocks that might not work anymore.

The player can generally only send objects along a single path because you only move in one of the cardinal directions.  Try using an object that doesn't have these restrictions.

Making the square block does not require using all three switches, but all will be used eventually.  The square block indeed needs to be made on the ground using the pistons/pushers, and if I understand your method correctly, you are already using the right two.  There is a way to hit both switches while you are still on the upper platform, let me know if you'd like more details.

Glad you enjoyed it, thanks for playing!

Just a heads up, S.5 will be getting an update that will hopefully reduce the possibility space a decent amount (I believe one of the fusions you've found will be blocked as well, but the solution shouldn't change much).  My suggestion would be to focus on making the square sticky block first.  As you've seen, you can only get on the upper platforms once (at least without using a bunch of pieces building a bridge) so try to get as much done as you can before dropping back down.  I know this is still very vague, so feel free to reply with any further questions you have.

Here's level 15 for Redirect: https://imgur.com/a/MhT4hkA

You are correct, you will want both the ball and chain on the top row before stepping onto either locking tile on the top row.  Try using the locking tile on the row below to reach the top; you may need to use this tile more than once to get the shape you want.

Thanks for playing!

Hopefully this helps, let me know if you want any further information.

Thanks for posting this, in this case this is the intended solution.  The extra box is there for a few reasons, but it basically comes down to appearance and making the solution slightly less telegraphed.  With five boxes it is somewhat easy to see where each one needs to end up and then reverse-engineer the solution (a tactic I would not usually discourage, but I felt it undermined the satisfaction of finding the "trick" here); with six the idea was that it would feel like too many so the player wouldn't know how many they actually needed to use.  It ended up being more jarring than I intended, especially when the previous 43 levels used pretty much everything provided.

You have to kill all of the enemies and then follow the purple arrow.  If you press 2, you will change to a teleportation ability that allows you to get through the wall towards the end.  You have to make sure your mouse is close enough (it will show a faded version of the character when it is in range) and then right click to use the ability.  Then you left click while standing on the brown circle to go to the next level.  Honestly though, you aren't missing much, this game is a worthy competitor for my worst game on this site.

Also, since I don't think I can reply directly to reviews, I'd just like to thank you, reading through your reviews has been a lot of fun.

No worries, it's basically just another way to say attached.

Thanks, that puzzle was a lot of fun to design.  A shackle is a piece of metal used to lock something.  In the case of a ball and chain, it would be the part fastened to the person.

Here's the solution:

Let me know if you want anything explained, I think seeing the solution without context might just make the level feel even more cryptic.

Thanks for reaching out!  There isn't really a good way to handle spoilers on itch, so below I have provided some hints that have been encoded using rot13 so that you can reveal them one by one (or all at once if you copy the whole thing).  At the bottom there is also a link to a gif showing the solution.

Thanks for playing Shackle!

Update 1 - April 4th

- Level 22 has been modified

Update 2 - March 19th

- Level 73 has been modified (thanks again to https://joel-fox.itch.io/)

- The undo sound effect is now quieter when undoing multiple moves in a row

Update 1 - March 14th

- Level 59 has been modified to remove an unintended solution (thanks to https://joel-fox.itch.io/ for pointing it out!)

Interesting, I was hoping the first three levels would establish the walls well enough, but I do suppose it would've been clearer if there was an early level that had more of them, presumably in a narrow corridor where the player could be forced to move around them.  If you have a rough description of which level the difficulty jump took place in it may be helpful.

Also, there is indeed a slight cooldown on movement unless all movement keys are released.  Said cooldown is slightly longer (still only around 1/3 of a second) following the first move after a key press.  This is to reduce the amount of missteps that occur.  The one that felt laggy is probably the one for the initial step, but without it, it is somewhat easy to accidentally move two tiles instead of one.

Interesting, that is similar to why I haven't bothered with GM Studio 2 (completely new and arguably clunkier interface).  It makes a lot more sense knowing that it is 8, I had forgotten that it used such a similar loading bar.

Cool game, the lighting effects are great.  I would like to see levels that are a bit less linear and that make use of being able to deactivate the switches, though I understand that you were working under strict time constraints.  I end up scrapping ideas and starting over quite often during jams, so I usually start with something like art or basic movement code that I can reuse pieces of in case I need to switch projects.

Also, just out of curiosity, is there a specific reason for using GameMaker 7 (I am assuming that it was used based on the loading bar) rather than one of the newer iterations?  There's nothing wrong with it (I am actually quite fond of 7, as it was the first engine I used), though it is definitely rare to see nowadays.

I finished all three levels.  I think the game would benefit from having the condensed light either be bigger (giving the player a better idea of what the map looks like) or slower (giving the player a better idea of what routes can be traveled down, which I personally think would be more interesting).  I thought that having to click the switch after finding it was a bit unintuitive, and I think it might be better to display a victory message of sorts after the switch is touched that can then be clicked to return to the menu.  The collision system was a bit annoying at times, especially in the third level, where the player often can't travel down a path because they are slightly misaligned.  I'd recommend making bigger pathways, snapping the player to a grid of sorts after movement (for example, you could round the player's x and y coordinates such that they are even integers), having smaller hitboxes, and/or making the player stop completely rather than bouncing back when touching a wall (this is probably the best option).

That makes sense, it started in windowed mode for me so it might be worth checking on another computer if you have the chance, though it could also just be on my end (which may indeed be the case since none of the other comments mention it).

Nice game, my only suggestion would be to put in a way to skip dialogue that has already been heard in a previous playthrough.

Great game, I would love to see this mechanic with something like moving platforms (or some object that behaves differently depending on whether or not it is visible) to force the player to be more strategic with where they stop the enemies.
