I love the promise of this concept and the use of the theme! Every death literally helping to make a challenge easier. Controls are really slippery though and lack finesse; I can slip and slide too far with just one tap of the movement keys which makes it tough when I accidentally jump into a hazard while trying to course correct, forcing me to reset the level.
Also there seems to be a problem with the screen itself, in that its so wide and tall that it can't fit into the window that I'm playing the game in. This makes it difficult to see what's below my character. The blocky simple art that's here could be effective in a Thomas Was Alone kind of way and does work at communicating the mechanics, but it could use a bit more personality.
