Glad you've decided to make this open source, I think the music portion may prove useful for other developers who would like to implement selectable tracks inside their games.
You are burn!!
Your games are getting better Lartar, this one is a little bit difficult because it's hard to get between the walls sometimes. If it was a little smoother it'd be pretty good.
I'm glad to see that you're making a lot of games for the site lartar. You seem to be learning quickly and I can't wait to see what you'll upload in the future!
To beat the last boss you need to hit it with a lot of regular fire and make sure to destroy the little saucers when they put a shield around him, but try to focus on the main boss as long as a shield isn't up.
