This is a cool idea for a puzzle game with some great ideas and mechanics. I think there's a little more scope for tutorializing those first few levels, but I really enjoyed playing this (especially when I got the welding tool!)

Oh yeah, I see the similarities but yours is also distinct enough to make it unique :) Obviously I like the idea of creating these electrical connections and the idea of "welding" unto other blocks makes is challenging as you have to think in advance or else is back to square one.

I want to share some tips I've learned making puzzle games:

• When possible, create levels that do not lead to a "locked state" where the player needs to restart thus reducing the frustrations of having to restart the level and feeling the dread of having to remember all the steps to get to where they failed (usually only to repeat it and have to restart it lol)
• Make the controls smooth and precise. There's this weird bounciness to the movement that makes is distracting and I even managed to get stuck because I thought I could move only the game was not ready for me to move (see the image bellow) Seeing that you are also using Unity and this is more or less grid based, I recommend using the "Vector3.MoveTowards()" method inside of a Coroutine for each grid movement preventing the player from moving until the block has fully moved.  This also allows you to coordinate with other game elements such as switches to interact exactly when you need them to. To prevent the player feeling like they are "waiting" for things to happen after they move I would recommend shortening the animation times on things like buttons and the pusher things to make them feel snappy and responsive. 
• You started very well with a short and simple level to get a feel for how to play the game but then level two felt more like it should've been level 5 in terms of the scale and how many things you needed to do to win. I recommend making more in-between levels that slowly increases the size of the level and the complexity to not make it feel so jarring and overwhelming to some players. 

Hope that helps and I mean this in a good way to help the game be even more fun post jam. :)

It's a good puzzle game, that last one really had me thinking.  However, I do feel like there's no real snap to this grid-based movement.  This made some elements (including that last puzzle) hard to impossible.  I think if the character snapped into place in a more grid-based movement (instead of this weird hybrid fealing that you had going here) you can make as many puzzles as you want.  Other than that, I do think that the welding torch should come with some kind of detach option, but that's just me.  Other than that, it was just fine.

Graphics and physics would need a bit of work, but the mechanics and level design is really cool ! I like how you nailed the tutorial, effectively teaching the mechanic while already have fun puzzles to solve. The interpretation of the theme is cool too, with graphics actually matching the circuit board theme it would be really great !

I liked that the puzzles were fast paced and connected!

Really neat idea and great level design! I loved it!

some of the puzzles really got me- happy you had a way to restart the level but great design!

Nice puzzle game. By the way, I noticed that you made the player magnetize to the middle of the tile so that you can easily climb between the walls. But because of this, I experienced some difficulties. Try to reduce your movement speed by mini teleporting player by 1/10 of a tile. May be this will help

Amazing game, if there was an undo button that would be better, but still it is fun.

The puzzles were super fun and endearing! Loved the concept.

The game mechanics are quite interesting. I like the concept of a puzzler to join stuff and complete the circuits, but I think it could be better presented with maybe a better choice of art or changing the default unity scene background colour yo something else. :P Great work nonetheless!

Art is a bit weird, is that a roaming pair of binoculars? anyway besides that the puzzles are quite cool and have some interesting  depth to them gj :) 

I'm going to be honest and say that I wasn't expecting to like this game. The graphics were a little all over the place. But the gameplay on this was really good, especially with the mechanic of permanently adding  pieces to your robot. This is one of my favorite games so far, good job!
