1. The artwork is the best I've seen so far around here, kudos!
2. Loads quite slowly, but I assume that's just the awesomeness of point 1 that's coming through.
3. The controls are uncoventional on pc: pretty easy to understand, hard to actually master.
4. The difficulty ramps up massively, try and balance it out a bit.
5. Despite the overall aweome graphics, change the orb that's fired every x seconds to something a bit less clich�.
Overall awesome game, looking forward to future releaes!
