Photon is a game for the Sord M-5. It is currently in development. Check out the video below for a brief demonstration of how it looks. The video was made May 21:st 2015, I have since then added a few more features, like scoring and powerups. When finished, the game will be released on cartridge and digital download for use in the MESS emulator. If you are interested in the Sord M-5 computer, I suggest you join the SORD Computers facebook group.
