Yeah, there was no error message for the crash. It happened during the quest to clear the fields. Maybe I was starting the random encounters too quickly? I was doing the quest near the end of the demo, and I was clearing the encounters in the West Field in 1-2 turns. I just ran from one encounter to the next after changing to a lower level form to get some levels for them.
I'm not sure if there's a system for it yet, but I couldn't swap my party members in the menu. I brought everyone with me after unlocking them, since I noticed that they still get EXP while participating in combat.
There are a lot of inherited skills on Human form. Maybe a way to arrange the skills might be a good idea? I wasn't using some of the skills because they were situational, so being able to move them to the bottom of the list would be nice.
I have some difficulty finding some of the materials needed for the Weapons Shop and Armor Shop quests. Maybe an in-game hint on where to find some of the rarer materials might be good?
The encounters for the campfire part of the Wolf unlock can be rough if you get unlucky with the random encounters. Getting 2 fairy enemies in a fight is a struggle, especially when all your attacks start to miss from all the debuffs the fairies give you. Maybe adjusting the cooldowns for the Wolf skills might help?
The boss for the Manticore unlock feels like it does too much damage with String Shot. Since it is a multi-hit attack, Withstand Attack doesn't help much. I had to use Rebirth to survive one from full health, and I got lucky with the second one when it missed.
That's all I can think of right now. I'm looking forward to the early access version when you release it.
