Thanks, yeah! I'd love to make another game with characters that you get to know. I really liked that aspect of Monster Mind but it's a tough balance to get right!
honestly you could do what InsomniacOvrlrd did and port your MM-verse characters’ personalities to an original setting!
when IO was DMCA’d by Nintendo, instead of deleting everything, they made their own setting called Passiontail Isle and retooled their established recurring cast there as fakemon.
Same personalities, same names, I believe, possibly even the same plots. But copyright-friendly.
