Thank you so much! I'll respond to your points real quick!
1) I'm afraid to make the boss any more difficult, but I will be changing that skill so he doesn't get stuck doing that one thing over and over. I'll either give him more mana, or make it so he takes a full turn to completely refill his mana.
2) Ice wolves might need to be fixed! There's a pack of them guarding some useful equipment, so fighting them might be important. If people think they're too difficult I may make them easier.
3) I agree! It's hard to make her a guaranteed target because of how RPG Maker MV's system works. I think it will be fixed in later versions though!
Thank you again for the kind words, I'm really happy you like the game!!
