@randomphantom, thanks for your comment!!! I used FMA for the music, no software :p http://freemusicarchive.org/mu...
I copied from the best: Listen to "Bust this Bust that" from the same artist, that's the music from... Flop Rocket :)
Not sure what you mean by the controls - do you mean the middle button to shoot is awkwardly placed? I kinda crammed the controls per player together on three adjacent keys, because the game is meant to be played three people on the same keyboard - as a result it's best to keep the space for each hand tight! In single player you can play with the mouse, which gives you a bit more precision.
