Awesome game, keep it up. My only issue with it was the controls, which were a bit of a pain, but otherwise excellent. Felt like I needed more air control, and the controls for keyboard weren't ever shown, so I had to feel in dark to find the right controls. There was also a bug where on respawning, the old music would keep playing, and I'd have multiple soundtracks running at the same time.
Loved the colour scheme, the short cutscene and everything in between.
