Thank you! My friend Zeocin and I are going to look into compatibility stuff once I'm done patching Chapter 2, but I can't promise anything since I've never tried porting games before and don't have very good ways of testing or fixing it for other systems... that said, there are programs for Linux to run Windows applications- I don't know if it would work with Monster Mystery, but you could try using Wine or an alternative and see if that works for now >vv<
First of all, thanks for trying it with that! It's good to know it works >vv< I'm glad you had fun!
Yasei squints in his idle animation which I know can look a little weird if you don't catch onto it >vv<; There are PP restoring berries you can sometimes buy at Ms. Lagombi, though they're pretty expensive- I recommend conserving your PP by using Standard Attacks when you can, that way you can have lots of PP for when you need it! I think if you ask Yasei for the Guidance called "Making Attacks" it goes over that, in case you need help there :3
Also I recommend using Tactics so you can tell Yasei to run away, or give him an herberry, etc, it helps a lot! Thank you again ^vv^
