Nice original concept, though I would prefer that "up" always was jump and the arrow keys move according to the view of the character, not the player, but I liked this. I'm guessing you like Portal.
I'm afraid that I didn't get the story. The game has the same concept of plataform games with the gravity theme (jump, avoid and switch the gravity), so for me it's nothing too new or interesting (not for voting, as an opinion).
Even thought this issues I liked the difficulty off some levels and it's good the way it's getting harder (not fastly, you let the player get adapted to the game as harder it gets).
My overall voting it's of: 8/10 3/5
Reminded me of cool old-school hard(but not impossible) platform games.
make the arrow go faster cause I accidently restarted my game
I see why Level 18 gets a medal...because level 19 you lose all your hair from pulling it out. :) Fun game. Nice Effort.
