The artwork is beautiful. Absolutely rich backgrounds and great character design. Animations are functional though a little sparse. The music is great. However, I do wish there were some sound effects to give queues to stuff like taking damage, and a sound effect when your character touches down from a fall would have helped sell it.
As far as gameplay, obviously you guys had some time constraints on your programmers which limited your options. I do have a few critiques about the design of it though. I really like the crumbling platforms, and I think they are easy to visually understand on a first pass. On the other hand, the design of your enemies causes problems. Our girl's range is just too short to be able to pass enemies without taking damage (at least for me).
Overall, extremely well done.
