Well we haven't had a game for a little while, so it must be about that time.
Here's one that I like. Mainly because it features the excellent Ren and Stimpy. But also because it happens to be fun and nicely done.
The controls are very simple: Up and Down arrow keys to position the cannons angle then hit the SPACEBAR when the Power is at its strongest.
Additionally, hitting SPACE while in the air you can get a little boost (if you have some farts stored up).
