Atari 2600 game coder “atari2600land” has updated his rather new homebrew game “Library of Doom”.

Release notes:

Thanks for taking the time to write the minikernels, Mike. I really appreciate it. Here’s the latest version. This includes the ability to shoot downwards, and changes the game screen to white. I still have some work to do on this game, but I want it all to fit in 4k.
