Awesome game! Since it's built in RPGmaker 2003, I got this running on my Nintendo 3DS via EasyRPG/Easy3DS, and although the music lags sometimes and the 3DS crashes on exit, it's surprisingly playable.

Needless to say, publishing builds of this game on 3DS is hard to justify, but the other commenters who want this game on mobile should know about the Android build of EasyRPG. (The iOS version is practically nonexistent though; I'd be surprised if anyone can get the game running on iOS.)

Thanks! This worked great for me.

Same issue on arch (steam deck). Couldn't launch through Proton either
