It's the spiritual successor to the classic game "Bruce Lee" for C64 (and Atari 8-bit). A new version was created in 2013 and ported to the C64! I went ahead and put the image on my SD2IEC device and played it on real hardware....and it is FANTASTIC. Flashier graphics, but the gameplay is very similar to the original.
Has anyone else given this a try? It's easy to try on an emulator. I could also create a floppy for anyone if they don't have an SD2IEC.
