I have to start with that you got me here with the preview image, simple and clear. The styling of the game into 2 colors is nice and but maybe you should have played around with shading a bit more because the scenes look a bit too much flat. In the second level where you get to the first bigger pit, I couldn't distinguish what is the pit and what is not. Only other problem I've had with the gameplay was that the the 2nd level was way too long, and therefore I wan't able to beat it without any checkpoints. There were many tricky sections in that level that I wasn't able to pass consistently enough to beat the whole level. Maybe if you split the levels into shorter segments, and allow players to fail faster without that much punishment it would help the game. Overall really nice gameplay loop that could be nicely expanded into longer game. Great work :)
