I've decided to make this an iOS game again. I currently have 40 levels (25 main and 15 extra), I plan to just keep making levels in my spare time to eventually get a whole censor-load of levels.
I also plan to redo all of the music personally, so I will not have to worry about Mr. Riley getting upset at his music being used in a commercial game.
Priority number 1 now that I have the engine fixed up is to implement the story via cutscenes. I actually had a story palnned out before I made this game, but never got around to putting it in.
After the cutscenes, I will work on save/load, possibly high-scores based on death count, and possibly make a website for the game.
