A brilliant concept well executed.

Well, at first, I was taken aback at the main menu (really!). I could hardly read what's written!
But when I started the game, those thoughts disappeared. The gameplay was immersing! The concept and idea of the game is brilliant!
The graphics are neat, and the music is appropriate. However, I found the dying sound to be a little, well, weird? Otherwise, there's nothing to complain about that department.
The controls are simple yet effective.
The level design is good as well.
But the game's more like a puzzle game than action. I really didn't find anything related to action (of course, I did not play the whole thing yet).
I give this game a 4/5. Good work.
