Space to shoot. Up and down arrows to move. Don't let the crabs touch the red line or else...
Thanks to Squirtle360 and fastrabbit. This is my first non-pong arcade game! Please like, love, and remix. I will make more versions of this. UPDATES: 5/29/15 v1.3 Added level variable. 5/27/15 v1.2: Level 3 is more difficult. Also, I added sounds and a better backdrop. 5/24/15 v1.1: The difficulty now increases as you play.
