The art and music was really well done. I was impressed when you introduced that falling down looped you around the screen because my thought process was "Oh I can't get those crystals whatever I'll get the ones below- OHHH".

The keyboard controls were a pain though. I kept wanting to hit space for jump and I had to shift around my normal keyboard finger placement so that my pinky wasn't on the Z because it's awkward and it started to hurt. I would've liked if just pressing down pushed you through the platforms instead of having to press jump as well.

Great Job!

Looks good, sounds good, screen shake is a bit too violent :D Restarting from beginning made me quit earlier than I wanted, it's a bit tedious to go through easy beginning levels for some time just to get smashed in few second on one of the harder levels. But I really enjoyed this game! At first it felt too hard but it's great fun to try again and again and do better each time :)
