Here's a Shoot 'em up I'm working on atm. Nowhere near finished (in fact only started it the other day). Missing some effects due the free version limitation and I'm yet to set all the alien patterns for the first level.
I've developed it so that I can just switch on or off certain attack patterns based on time, which is a lifesaver when creating waves. The health bar works but doesn't as you can't die yet (got fed up of dieing while testing :P ) and the big lazer is way to powerful, would kill you in a second.
The shot speed changed after a few seconds because I was trying different speeds and set it to a timer rather than waiting for a certain event.
I've ran out of events in the free version so this is another game I'm putting on the back burner until I get a license. Anyhoo, tell me what you think.
EDIT - I uploaded the wrong version :P
