I enjoined the little triangle. and the tutorial that proceeds as the level goes.
The idea behind the game is also cool!
A small suggestion if you plan to work more on this project after the jam: I found not so intuitive the fact that you can run on the walls, now I see the animated gif, but when I entered the game it took me a while to figure it out.
Anyway, good job!
P.S.
Leave feedback also to my entry, I would really appreciate it!
