Somebody made a mod of it for PortMaster, with some music changes and I don't know if anything else is different. I don't know how that works though, I've never used that software, but multiple people have been running it on different hardware. You can ask them in the Discord if you're interested.
Hi, the only changes I made for the port (not a mod) are bgm music swaps and adding Q and E and keyboard options for scrolling through cards. Everything else is untouched. It's had 1,970 downloads since publishing :)
