I appreciate the input and glad you're having fun with the game!
Battlebacks will be included in a future release based on player feedback.
At some point I'd like to import some sprite animations out of MV as well, as the MZ particle effects were used out of convenience more than anything.
Your comment definitely got me thinking about the sound FX. I wasn't planning on prioritizing that aspect until much later on, but I agree those RTP sounds could derail the retro vibe a bit.
Looking forward to hear your thoughts after completing a playthrough.
