Thanks, easyname. I think I see what I was doing wrong.

I like the logo, aside from it being too loud. My main problem is learning the differences between AS3 and java. Does the spritemap's flipping work or am I just using it wrong?

You could have a level up kind of system. At the end of the floor you get a bonus sword, shield, or something. Then, the ones hidden around the floor would be a bonus on top of the "floor complete" reward.
