I loved it, it's really a concept worth pursuing, you've got something here.
The 3Cs are perfect, it's incredibly satisfying to gain in ease and speed. The tutorialization is cool, the art direction works well (even though it only uses a single texture x), and the final twist is a very elegant way to end a jam game.
I've always wondered if it was possible to make a horror game with a very high range of motion, or if the adrenaline rush of fast fps would stifle the possibility of being scared. This game doesn't necessarily answer the question, since it's more of a puzzle game, but it gives me some clues...
