You know, if you do make a full game based around those characters, I'd play it. Though I am guessing that if you are tired of RPGM, it won't be until you learn a new engine... ^^;
Sadly, no. I planned to participate and even cleared the time, but then the town where I live got hit by two consecutive heat waves -- my brain basically melted down on Friday and didn't fully recover until Sunday, when it was too late to start from scratch. My participation mostly boiled down to rating other folks' games this time around. :-) Here is hoping that GMTK Jam 2022 will take place at a later date, when the weather over here isn't so extreme...
