Bravo! Very cool to see such a good passion project! I was able to beat the demo once I figured a few things out.

Exceptional graphics and effects. I was really impressed by the changing camera angles while playing. Gallery and Simulate features were both nice additions. Difficulty was reasonable and not too much of a "bullet-hell". The boss animations and water level were fantastic. I don't think I've played a shmup that took place underwater before. It was very nice to see organic enemy types.
Suggestions for Improvement:
I was pretty frequently confused with selected buttons being highlighted in grey. Usually one associates green with "go" so when a button was grey, it leads one to think that it hasn't been selected yet. Also I found the moving menus to be more annoying than cool. The player ship voiceover sounds a bit canned.
Overall: Very impressed, if I didn't know any better I would have thought this was a AAA title.
