This is cool. I really like the visual style. I think it would be nice if PP filled up when you returned to camp. I would also like to transition between the tower and camp without having to go back to the title screen - but I'm sure that's something you already noticed and am working on.
The first person camera was a lot of fun but I also found it disorienting at times. When playing the Fighter, attacking moves you a few steps forward so it was very easy to lose track of my surroundings in the more difficult encounters. The fire mages were the hardest enemy I came across. Much easier in third person than first - because attacking them at melee range sometimes pushed me too far ahead and I could no longer see their tell.
The environment looks great though. I love the atmosphere. Can't wait to see more.
