The games made by PervyFantasy use the SRPG studio engine to make games so those definitely fit the bill. If you don't mind japanese there's also a number of games there that use SRPG studio like We Are Bandits.
The best one IMO is Aldo Senki which is free on pixiv and is also primarily Japanese. It has an English version but, its MTL, and it only translates the main campaign. The second half of the game, Aldo Senki Gaiden, is IMO one of the best mind control/corruption games that I've played. Just be mindful that, assuming you play the game, Aldo Senki is really long its like 40 chapters for the main campaign and 20+ for the Gaiden although Gaiden isn't complete yet but still being updated. Hope this helps!
