Very creative idea! And I love the sound effects (low, medium, high pitch knock when changing state for example).

My only issue was the box to cover the screen was in the way a lot. During levels it was small but would cover up the right quarter of the screen, and in the menus it covered half the screen so I couldn't play half the levels :O. Which is sad for me because I'd love to play more levels haha

This was really well done! I don't know if this was a problem for anyone else, but the scale of the transition objects was off so I couldn't play some of the levels. But for the ones I could play, I loved the mechanic and the level design was great (but it was hard at times). The effects were also really good, especially with the text.

I love it!  It is far too hard, but I love it!

Very good game, one of my favorites, but screen size is to big for me

This is probably my favorite. The switching mechanism is well done. Most of the levels are well designed. I like Switch State graphic a lot. Good Work!

Level 15 was awesome!!! I loved how you could use the phase transitions to change your momentum. The last level really pushed that concept. I almost wish the entire game was a "change phases to race time" 

Great game and a very unique concept! 

nice

I find it really hard to estimate how much matter I have left, maybe an indicator for that could be good?
