This is an NES game based around a robot designed to be a serial killer
The scrapyard.nes file is intentially not ignored so that the current build can be downloaded even on a phone or computer without a compiler.
However, a released version will come out once it is done.
This requires CA65. You'll also need make to run the build commands.
From there, it's simple:
make
Then to run:
make open
Or, open the newly created file scrapyard.nes with an emulator of your choice!
Run compile.bat and it should compile and try to open the program with FCEUX emulator, which might fail
