Spacewar? is a game I made in around 10 hours for the Lost Cartridge Jam 2021. It is very loosely based on Spacewar!, and was made in GB Studio. I would have preferred to include the original game, but I had neither the time nor skill to do that. In regards to the theming of the Jam, the story behind this cartridge is that it was made as a proof of concept for a larger arcade game based on Spacewar, with multiplayer, more enemies and levels, and additional features. Upon being received, it was looked over and garnered a positive reaction, but was forgotten and the plans for the arcade game fell through.
