I loved it!!
Crazy game, it's a really cool feeling to get stuck with a very little timer, and have the need to "farm" more time in early levels, I didn't get it at first, but it didn't take me too much time to realize haha
The unlocked mechanic in the end seems like a little thing, but it's not, it was a great way to give a little replayability and extend the game's time
Also, you had to think about it in the level design I'm impressed, it allows taking massive skips in levels 1,2,3
Idk if I broke it but I had infinite jumps in the air at one point
My score (after looping and improving times): 4275800
Great game, great audio and visuals, good job :)
