Much appreciated & thank you for the kind words (+ reporting some issues)!
There were a few bugs that I couldn’t squish in time (like the ones you mentioned) but the debug tools for GB Studio are surprisingly robust, so I managed to fix those (eventually)
As of the latest update: now there’s also a little indicator for the Attack Minigame that shows exactly which Pixel it stopped on when pressing the A Button; quite useful for debugging and also Player feedback!
Bonus Fun Fact: the Severance-style look & setting also helped with the unique tile limits (only 192 8x8px tiles per Scene) on the Game Boy, so it was a (semi-)perfect match.
