This was a very cool little game. I love how you implemented the there with the 3 abilities with the different timers, and the reminder at the bottom left was a nice touch for that. Artstyle was very cute and the music was good too. The trick with timing your abilities so you could switch to another one was a clever way to add challenge.
I couldn't get past level 4, the timing for the jumps was just a little too tight. I kept getting tripped up on the part near the beginning where you have to switch from jump to speed because the height of the super jump puts you right in line with the crusher so you have to jump just right. I couldn't get past the part where you use invincibility to fall through a narrow tunnel of spikes and then activate it again before you hit the ground, couldn't time it to run out while I was still in the air and it was tricky getting back to that point to try again. Got blindsided a lot by new challenges, especially if it was something below me. Midlevel checkpoints would be much appreciated. Altogether, very nice job!
