I've also noticed if I turn the camera (with Left or Right) right before a battle starts, the camera turns a few degrees and then ANOTHER 90° after the fight, turning it slightly more than 90°. I think this is related to the RPM engine though.
Also, since I'm able to walk on <=45° slopes, I could walk around the Magic Stones Lake; not a bug per se just funny:
I do want to say, I absolutely love the map designs and atmosphere of the game!
It feels so vibrant and full of life, I am thoroughly enjoying that and I don't think I'll ever make an RPM game this full of style and with maps this lovely!
