Thanks guys. Gogetax, can you post your specs please, I don't understand why your fps drops sometime, on my two computers (the 2nd is a 2 years old laptop) things are running fine.
Things I have to code:
3 or 4 more levels with news ennemies.
New weapons, and other features like a time limited invincibility.
Main menu.
A better animation when player loose.
Better big explosion for boss.
Space key for bomb for mice with only 2 buttons.
A better player damage system. (with 5sec invincibility after been hit)
This will take 2 weeks I think...
