Nice game. The platforms are kinda hard to land with the controls, maybe a bigger area or coyote time would help, the graphics are nice and audio sounds great. Good concept for a start.

Audio was pretty solid, but the controls made it very difficult to handle the small platforms. I could barely make it onto the smaller platforms before getting rocked (Sometimes literally :P)

But it is a neat little concept, If you had a finer level of control in the air, maybe by using "Oxygen bursts"  and increasing total O2 count a bit to compensate, this has potential to be much more enjoyable.

The level design was good! It felt like the levels were always leading me in the right direction without holding my hand. The controls are too floaty though for the tight platforming. I played for about 15 minutes but couldn't get past level 2. The audio was good too! Set the tone just right.
