I tried but for what I want to implement the hardware is way too primitive (as well as my knowledge of it still). and real life keeps interrupting me. I hope to make the next one.
I decided to release what I have, it' s neither polished nor finished. Use arrow keys to move, fire button to shoot, and space bar to add more enemies. After 10 kills you evolve into a larger bird. There are missing features and title screen I wanted to add but I'm out of time. I hope this submission will suffice. Can use altirra.exe to emulate it, or a real atari 800 or XL/XE.
