Huh, wonder how I missed this thread. This sort of thing is a guilty pleasure for me having worked on similar things as a teenager, but so many of the recent ones are just.. bad, to the point of being unplayable. I'll power through them if the combat is fun though since a lot of them actually put time into having fun relics/combat quirks.
Here's a couple older ones: (warning! spoilers for pretty bad games)
Virgo vs The Zodiac : Fun combat, developer runs out of steam hard past the first few areas and basically pulls a Xenogears Disc 2 for the back half. Also there's a lesbian romance where one of the lesbians dies in one of the most unemotional death scenes ever and a huge depressive character arc as a result.
Ikenfell : Fun combat system with really good equipment/skills, great pacing, decent plot, goes way too hard on LGBT characters though. The final boss fight involves
beating the shit out of a gay man having the most stereotypical histrionic gay meltdown possible which is amusing. You also get to fight a really gross giant sphere of clotting blood/tumor mass at one point, and I appreciated a little Binding of Isaac grossout thrown in as a complete curveball. Ikenfell deserves a special mention for having drama over a hidden boss that the developers were dropping hints about being in the game (complete with there being quest items related to said boss, etc) only to have someone on twitter call them out and post datamined proof that the boss wasn't actually in the game, leading to one of the people running the twitter melting down.
Jimmy and the Pulsating Mass: Got mentioned earlier and is the only one of these three I'd recommend anyone playing. Its biggest fault is that it's a 60-hour game paced like Earthbound and as previously mentioned, the big plot reveal is in-your-face obvious. It's a game about the journey rather than the destination though and doesn't pull its punches with horror. If you're like me and actually like grindy classic JRPGs and equipment optimization it's a great time though and deserves credit for pushing the RPGMaker runtime to its absolute limit.
If you bought any of the giant 2000+ game bundles from Itch, Jimmy is in them, so give it a shot if it sounds like your jam.
