Game aesthetics are brilliant, especially art! The theme is pretty depressing but interesting.
Unfortunately, I had some trouble with the main game mechanic - jumping. For me, it is not enough feedback about how high and in which direction I will jump. Because of that, most of the time I've heated the walls rather than jump on platforms and move further. Would be nice to have some additional UI elements that help me understand how exactly I will jump.
But still, the game is great and I mostly like it!
