This was a trippy experience, and a really unique concept! It took me a second to understand that it was a two-player experience, but even controlling both sides of play is neat in its own right. The fluid simulation and audio are done pretty well.
It may help to color code the players in some way to correspond to the color of their jets - with a lot of turbulence on the field and little activity, it can be a bit difficult to tell what's going on. I sometimes also felt like the power-ups might have spawned too close to one gate or the other.
Neat game, good job!
