Some work on tiles for my short-term shoot'em up project. I've just recently finished the code for solid objects and how the game deals with the player crashing into them--you only get hurt by them if they force you off the edge of the screen--so I've started brainstorming level ideas. Needless to say, what I've done so far is very basic, but I will hopefully continue to make progress.

UPDATE:
I added a lot of detail and changed the backdrop a lot. I left in a few tile variations.
