Very cool game! I love that mechanic about 2 different dimensions with or without mouse a lot, very unique!
I would change the player controls tho. Having to control the mouse and try to prevent the character from falling at the same time it's pretty tricky. Not a bad mechanic by itself but I think it made the game too hard and you'll only get hardcore players.
I wasn't able to pass the first level. I want to try this game again when I have more free time to play, because I think it will be very cool to be able to complete it. Thank you for making this game!
