So I just tried this for a bit and the new version has a pretty big bug where if any attacking skill is used, the game freezes. This happens against multiple enemies and due to the fact that Lamia always goes for poison slash I can't get past her this time. The only skills that seem to work are fancy footwork and the fairies' light heal.

I forgot to keep my save file from last version so I can't say anything about the second dungeon and new party members yet.
