Hi, is it OK to include this game on the DOS Games Jam Demo Disc (an ISO that users can burn to a disc and play on a retro PC)?
Sure!
Just to make sure it works I redownloaded it. Turns out it was missing a key file to run. It's been fixed now and should run in DOSBOX/DOS as much as a hacked together LUA/C++ game can.
If you're interested in others, the games LUATRIS and LYFE are programmed the same way; using LUA/LOVE2D with LOVEDOS (a LOVE2D mod) to work in DOS and you're welcome to those as well.
