Really cool game! The gravity switching mechanic is really good idea. The slow mo mode is also nice but it seems like it could be abused very easily. You could maybe make it so that the slow mo can only be held for a certain amount of time. Also, I would have liked it very much if the arrow keys were able to change gravity too. The text in each room, and the little story it tells gives the game a lot of charm. I especially like the idea of having to go back to the main menu a couple times to beat the game. Though the game lacks polish in certain areas (particle effect, screen transition, etc.), I had fun, so nice job!
