This is awesome so far!
Noticing a couple bugs with the battle menu:
1. If I use the joystick to navigate, the menu "resets" and slides in from the right on each directional press. See this video.
2. If I use the D-pad, navigate so that "Bag" is selected, and then press D-pad left again, the selection gets stuck on "Bag." The only way I've found to unstick it is to use the joystick instead. (Don't have a video of this one.)
I'm using an XBox One controller, in case that matters!
