Chris Cacciatore is heavily working on his NES game Nebs & Debs and hopes to have it ready in late spring 2017. The game itself is a platform game. For now you can run, jump and collect diamonds.

Progress:

* Game can now be paused (using upper bits of PPU_MASK to darken screen).
* Crystals glow using palette swapping.
* Scenes can now encode palettes (used to just be hardcoded).
* Progress towards transition screens before each level (where you see your life total and the level name).
* Bug fixes.
* Minor optimizations to reduce ROM size.
