Something made perfectly for me - I like platformers, but I'm terrible at parts that require reflexes. This is an amazing approach to combining puzzles and platforming. At the beginning I had to take a bit of time to get used to the game, but once it clicked, it was real fun. And a pretty good puzzle design too!

Pretty cool game ! The mechanics are really innovative

I like the mechanics, but I kept encountering a bug where he would be stuck midair =/

Good level design!

I'm digging it so far!

I think I got stuck on level 3 for a bit. It would have been nice to have a slightly clearer tutorial about adjusting your jump height by bonking your head. It'd also be nice to have an indicator of what level I'm on. I think I was stuck on 3, but honestly I don't remember. Also, if I wanted to ask for help with my current level, I'd have to take a screenshot and share it.

Generally, the gameplay loop is fun! It's high-risk because you have to get the solution right from the start (very Celeste and Katana Zero-style), but restarting a level is easy once you realize you've messed up. The graphics are fun and cutesy, though I'd prefer Mr. Blobby (that's his name now, it's been decided) had a little more spring in his step. Jiggle when he lands, wiggle when he moves, and speeding up the walk cycle animation just slightly would go a long way.

The music is simple, but it fits the art style. It feels right. I've just had it going in the background for ~15 minutes and I think I could listen a bit longer. Not too much longer, but I could probably stand this music for ~20 minutes or so.

Really interesting mechanic, I got stuck at level 11 but skipped it and finished the game. EDIT: solved level 11 thanks to screenshots :)

As other have said, the UI definitely needs some work (like when you get stuck on a magnet you have to click) but the graphics and gameplay are really nice.

I completed level 5.  I couldn't  complete level 6.

Love the idea of this game! Puzzles are fun to figure out.

Nice work. I enjoyed what I played.

Suggestions:

• The potential energy stuff should be explained more clearly early in the game (either purely through the level design which can demonstrate consequences or more clarity in the hints).  I was quite confused for a fair bit of my play through. 
• I assume the UI probably wasn't the focus during the jam (which makes sense) but it was a little frustrating that it could not be controlled by the keyboard. Also, regarding the hints it would be better to have them activate on entry to some collider and then deactivate on exit without the player having to manually close them with the mouse. These kind of things would help the game flow better,

I see that you are looking for constructive feedback so I tried to focus on that. Overall my experience was quite good. Well done.

I really like this, puzzles are really good and got my brain working, if this ends up a full game it would be interesting to see how all the other features fit in so would definitely play that,

My only tiny criticism would be the tilemap you've used, the character looks really nice, but I feel the tiles are maybe a little too square, I feel if you added a few extra tiles to the map which would help round off the sharp edges, in the same way the characters edges are rounded it would make it look a lot nicer.

overall though it's really good, congrats :)

This entry is so good :D the puzzles are well thought out, take some thinking and make this a lot of fun to play, best I've played yet.  It sounds great and looks pretty cute too, I think you should go for it with developing this - not seen this idea done before and it's really cool! I'd defo buy /play it.  Love the idea of using ramps for momentum and thinking about how to reduce momentum to get through certain gaps

- Might be worth adding a little bit of text in the corner indicating what level you're on and making the level selection a bit easier to navigate with maybe something like levels 1-20 on one page 21-40 on the next as boxes or something, but all very minor points - really good job on this!

Absolutely not disappointed! You went the most original mechanic of the jam and I think it must have been pretty hard to design those levels. I would like to have seen more gadgets to play with but I totally understand the time constrains.

The gameplay was excelent albeit some of the controls were a little off. I'm just nitpicking here though. There was nothing that a quick restart could not fix.

Graphics were totally adequate. Nothing wrong to point there and the color scheme was on par and absolutely clear, just like a good puzzle game should be.

Audio was excellent. Cudos to your music guy. Well done!

I really have not much to say other than you should totally move forward with this concept.

Finally something with original mechanic.

though wasn't the most eye caching this game might be the best one i played so far in this jam, tile based platforming with your potential energy mechanic makes this game one of a kind (im tempted to make my own idea based on this idea). i never seen this idea explored but it's kinda incredible. 5 Stars from me. and i hope this game develops further and ill be more than intrested in helping you with such a project as well i like it that much.
