I made this game for a class, it was an interesting experience.
My group was supposed to help me a bit more than they did, and it just didn't really happen until very late in the semester.
I decided to turn it in pretty much as-is from what my class got to play, so it might be a bit rough around the edges. I had to rush to finish it, even though I provided my group with the level editor a month or more before it was due.
My group contributed the tail-end 4 levels, the title track and beam sound effects, and some art assets I forgot to implement.
Regardless, I hope you enjoy it.
