Brilliant. Stylistic. Minimal. Great UI, typography and art direction. Love the water effects and feedback, the physics are great. Would be nice to get some feedback when hit (minimal screen shake or slowdown / warning ui). Soundtrack is great. Would be cool to see enemys enter / exit the battle field in unique ways (like submarines arriving or mechs out of the water into the sky). Great scope for giant boss battles or levels where you have a lot more boost / less gravity. Really exciting!!! So... fluid.
