OK, I have actually been working on this, but as you can tell I'm not one to document my progress much. Here are some things I've gotten working (screenie soon, probably)
- Scrolling tilemaps - w/ RLE compression
- HUD at the bottom of the screen
- Hearts, you have three until you die
- Pills a la Fantastic Sam, the same as coins in a game like Mario
- Grayscale tiles
- Doors, locked doors, and keys
Quite a few more things i need to implement.
