For a puzzle platformer, the time mechanic is definitely implemented really well, although I think the different modes could've used an audio indication in addition to the particles, and the way how you use the in-engine physics to help create the level is really cool. Besides the mouse control issues people have already mentioned, you might want to add a failsafe in case the player sends the the player character flying off the map, because it's definitely possible in level 4 if you hit the leftmost booster at just the right angle, which I did in fact do. It's not too much of an issue though, because of the level select, but making it automatically restart the level or return you to your last point of not being off the map would be nice.

There should be a sound effect for each mode. For the flying of the map part, I hadn't been able to replicate it. Thanks for notifying me tho. Usually the fail safe would be to encapsulate the entire map with walls like with level 1 but I seemed to have forgotten it when making level 4. Thanks for the criticism. As for the mouse issue I mentioned this to others but I really wasn't able to do much testing with different mice. I do have a tweaked version if you would like to test it. You can find it on my page but please don't change any rating I just want to make it more playable
