Nice work!
I like the game overall, but I think it's a weird pacing. It would be nicer in my opinion if you could move freely... I dunno, it felt a bit slow paced and frustrating to control. Maybe just a faster normal gameloop would help. The graphics and mechanics worked pretty well, however, so no big problems there. There was a section that had no option to not take damage, which was a little frustrating, but fine =D
Awesome work!
