After a two month hiatus, I recently began continuing work on this game. I added a few things, but I want to add a whole lot more. So I think this might end up being an 8k cartridge. Tonight I worked on adding a second enemy in that shoots at you. Oddly, I got finished at about 3 a.m., but the previous night was spent trying to make what I have work on a real Odyssey 2. I FINALLY got done at about 7 a.m. yesterday morning, even though I started work both times at about midnight. I love my Odyssey 2 SD cart. It's great for testing homebrews I work on. I don't think I once played a released game on it since I got it. Here is a screenshot of what I have so far with the enemy that shoots at you.
