I see what went wrong. I uploaded the wrong .zip for the mac build. It should be fixed now.
Thanks for fixing this, it’s a fun game!
FYI the executable inside the app doesn’t have execute permission for some reason. For anyone else who wants to run on mac, run this before opening: chmod a+x ~/Downloads/Rotund\ Dungeon\ (Mac\ Build).app/Contents/MacOS/ROTUND\ DUNGEON (or wherever the app is)
