Cheat sugestion
Instead of What is Love, try some other music that wouldn't fit, like
Something Classical... anything really
Theme song for barney with all enemies having purple tails
The Adams Family theme song with every enemy being uncle fester on the can (turned sideways)
Death metal, with every enemy wearing stuff you normally see at such an event, with the entire screen shaking, like an earthquake. Try to hit something with this on!
Theme from starwars, where your weapons become a lightsaber and a blaster. All enemies would be storm troopers.
Nice demo though, got to like it
