Very simple and nice! It's a pity that the triggers of the elements are small (or bug I don't know). And I unfortunately never got past the beginning of the second room with the cube pushed. My character disappeared it seems during a collision with the cube (I imagine) and I could not leave the hole.

With more playtest, diegetic indications in the environment you can make a nice game! :)

The graphics are simple but clean ! And of course it lacks sound (feedback and atmosphere). In general your game lacks a bit of feedback.

A last point, is my incomprehension in front of the choice of the key M to interact with the environment. Why not Q or E (in QWERTY version) ? 

Don't hesitate to contact me if you make a new version! :)

Anyway, congratulations for the general atmosphere ! :D
