Thanks for playing!
I already knew about the Zombie portrait issue and kinda regarded it as a low priority due to the time crunch. Ideally, I would have set it up so the portrait wouldn't be displayed at all, as I considered seeing their HP bars would be needless clutter when they're meant to be disposable.
As for the menu glitch, I legit had no idea what you were talking about until I was testing out the android release and ran into the same glitch. My current guess is it is some problem with the Battle Status Screen plugin that only happens on the web-based versions, as it never cropped up during testing. I'll be looking into what exactly is the cause of the glitch and try to make a fix.
