There are a lot of both good and bad things in this game. I'll start with the things that bothered me, and made it so that i didnt go to the end: nothing indicates that you can run with shift, so it took me like 8 tries on the first level to figure that out. you run faster diagonally, and given the timing are so strict, you have to do the levels by looking into the walls istead of in front of you. These are more minor problems, but i think the bigger one comes with the hitboxes: it often requires multiple click before pushing someone actually work, and if you walk diagonally into a wall, your movement gets completely cancelled, instead of sliding along like in most games (This situations can happen quite some times given you have to run diagonally so you have less controll).
Still i gotta say your game also has a lot of great stuff: the graphics are really cool, the sound effects are simply great, and when there are no walls nearby the movement is fluid and feels good. The story is also funny, although i didnt see the link with piet mondrian's tableau 1, but then again i didnt reach the end so i cant be sure.
In the end it's a game i like but it gets frustrating really quickly, but if you update it to give some more time, i'd be very happy to retry the game and actually finish it. (especially given i think the game is really fun if you can do the levels in 2 or 3 tries)
Anyway i'd like it if you would consider playing my game as well, and giving me feedback on it (and rating it also)
