Loving what you have so far here, but there is a pretty severe issue. I've only had it occur at the end of fight scenes -- 100% of the time when either Garuru loses the match or Seed in Womb goes above 100, less often but still fairly frequent at the end of any fight.
The error takes the same form each time: the stats all become 1, except for CON, which jumps back and forth between 1 and 0, the HP and LP bars climb up and down erratically, and the game becomes entirely unresponsive. Exit and restart seems to be the only option. Tribute to the game that I kept doing so!
Playing on PC with Windows 10, if that matters.
