Progress so far.

I've got the basic movement down for the main character and some collision detection. The collision detection really made me scratch my head. I have to visually draw it on paper for it to click. 

I'm definitely concerned about getting big enough levels into the game considering the main character is 16x16. I initially had devised a scheme to dynamically generate the maps using a string format, but that was really tough to design a level that way. Using the tilemap is just easier, and I hope to use this script to compress several levels into the tilemap area - https://www.lexaloffle.com/bbs/?pid=11383&tid=2092

We'll see how that goes.
