Realyy fun, and well-made! Good job!

Played it!

Unfortunately it crashed after the 2nd level

I liked how your character does back flips, slowing down time was cool as well!  :)

I don't know if you noticed or not, but the player sprite flips the same way no matter which way you face.

Also, I would make it so you die when you fall off to the left of the level, I was just stuck there until I reset.

Another thing I would do, turn the intro music down a bit.

I was using the controller and it seemed to work great!  :)

I think if I was using a keyboard I would'nt want "Q" to be slow down time, maybe something like spacebar.

Congrats on your first game!  Keep up the good work!  :D
