Wave progression
Enemy patterns change as the waves go on, so it does not feel the same every time.

Space Raid — CoCo 3 Arcade Shooter
Space Raid is a homebrew arcade shooter for the Color Computer 3. Move, shoot, dodge alien fire, and survive each wave. I am building it for real CoCo 3 hardware first, not just emulators.
Work in progress: Space Raid is a hobby project and will keep changing as I add things, fix bugs, and try new ideas.

About the game
What is Space Raid?
Space Raid is a simple, fast homebrew CoCo 3 shooter. The current build has several enemy types, wave progression, shields, and keyboard controls that work on original hardware.
The GitHub repo has the source, BASIC loader, ready-to-play DSK, build scripts, test programs, and project notes.

Current public base
Built for the machine, not just the emulator
The current public build is v42s. It has safer keyboard setup for real CoCo 3 hardware, keeps the normal shield system and wave progression, and has the falling shield pickup turned off for now while I track down a hardware problem.
Build it yourself
The repo includes a small 6809 assembler and DSK builder. If you have Python 3, you can build the game.
