With three days left......I'm pretty sure that I'm going to make the deadline :)
The main addition to the game consists of the boss fights, which are fights against your nemesis. He really is just a big red square, but again, I can't draw :p
He can change between attack patterns at certain HP points, which is a nice touch.
I also added really basic menu screens, including the pause screen.
I guess all I have to do for now is to add sounds and music, and create more levels. I could add more features, but I'm satisfied with what I made throughout the week :) Maybe cleaning the code could be helpful, since a lot of it is spaghetti...
