Hey, so this is the first thing I've submitted to NG in well over a year, and also the first flash I've ever had sponsored.
The game is called Fish Tank. It is mostly about figuring out what you are supposed to be doing, and then doing that. The controls are explained in the game, but if you can't get the hang of it, here they are again:
Use left and right to "swim"
Press back to slow down/reverse
Space fires your laser
Shift to pause
