Kielbasa Empire is a Commodore 64 game, currently in development since around September 2021. The game is about about farming crops, feeding pigs and turning them into sausages, however this could change in the future, as the game is still unfinished. You can download a .crt demo version from the link below. The .crt extension means it's a Commodore 64 cartridge image. Emulators like Vice and CCS64 run .crt files as well as Easyflash with a real Commodore 64.
