I really like this game! I think it does need a lot of polish and refinement, but the ideas, gameplay, and puzzles you've created are fantastic, and would make an amazing full game. I hope you continue to develop this further. The biggest thing I'd recommend is re-working the controls, it's incredibly hard to control where you fall and this made some levels superficially hard and frustrating

Well made!
Very smart way to implement a tutorial!
Mechanics were simple and very easy to understand.
Puzzles and level design Excellent! <3

I had 2 issues.
1. Camera - I know that this is a 3D environment and it looks great as it is but running out of a platform, or jumping int a wall was a standard practice for me :P. I am not saying that you need to increase the FOV for the game but maybe you could make it adjustable with an ortohraphic camera as max? (I know that is not something you think of during the game jam)
2. Air movement controll - very subjective topic but for me falling between walls was the hardest obstacle there was... Did you play/watch trackmania by any chance? There is something called air break which stops your car from rotating when you press break while in the air. Maybe adding a way to stop horizontral movement by pressing the opposite movement button (eg. A when going right) while in the air would make it more controllable?

Very smart way to implement themes!
Good job!

Beat the game in about ~40 mins and 178 deaths. This is a really well made game. The platforming is extremely precise, but the movement feels really good. The paths are really well thought out and fun to execute (except for level 8 which I think I cheesed). I love the art style, although since the player is 2D and the rest of the game is in 3D with a perspective camera, I would sometimes walk off platforms on accident thinking I would still be on it. That's about my only gripe.

Really well done.

Got to level 5 and really enjoyed the way the difficulty of the puzzles progressed. It's a nice take on a puzzle platformer that got me thinking at some points. The tutorial was quick and straight to the point which helped getting into game easier.

Awesome job!

This game was awesome! I love the art style, I was hooked from the opening cinematic. 

Awesome job on this game. I only got to level 3. I'm looking forward to coming back to beat it.
