Shoot down your enemies from your raft, and ultimately rescue your parents!
The objective of the game is to eliminate the enemies at every stage either by making them swim with the fishes or by dropping their HPs to zero.
A quick tip would be to full power and aim at a low angle. This way, you only have to adjust the height of the shot. Have fun!

Use mouse to aim and Left Click to fire.
Select weapons 1-3.
