Hey, sorry! I'm afraid I don't know much of anything about emulators and phone formats, unfortunately. I had never even heard of Joiplay (or any other emulators for that matter). The game is made in RPG Maker VX Ace, so if there is an emulator that will play those games, it should work, as it's a pretty standard game that I didn't do anything special with. If it doesn't work on any emulators, I really don't know, unfortunately. It would require the game to perhaps be ported to RPG Maker MV, which allows for mobile versions, but I think that would be quite the undertaking as all the plugins and code would need to be redone and probably the whole game recreated from scratch tbh 💦 That's one of the reasons why if I do ever make an RPG Maker game again, I probably wouldn't use VX Ace, as it's unfortunately somewhat limiting in that regard, I think.
