I made this game during my first few years at highschool. It is pretty poorly programmed, but a good start and I learned a lot from it. I wrote all the music, borrowed the sounds from several various free wav websites, and programmed the entire thing on my own.
Right now the game doesnt have an ending - but when you beat the game on a certain difficulty you unlock all powerups for that difficulty as a little bonus!
Good luck if you play it on hard, even I have a hard time with that!
Be sure to let me know if it works or not, and what you think of it!
Unfortunately due to poor programming this game actually requires a pretty decent gaming computer.
