This game could be even greater if the gameplay mechanic was a bit different. It doesn't have to emulate physics so much the way it does now. You rotate the character left right, upside down even... too much! and why does the character die if they touch the surfaces...? it seems out of context.
The feel, music, art all look great. But under different mechanic this would make it a very good platformer. it could still be skills based but this is beyond skill... you need flightschool skills to navigate the damn thing! :)
