Oh, somebody mentioned my games ! Nice !

(I'm the creator for Gaweb, actually Gaweb Studio)
Anyway, I was checking all my other "rivals" which is always entertaining and can give me some new ideas and found this topic.
To OP meh65, I see that you focus more on gameplay rather than graphics and story. Then maybe my free game would suit your taste perfectly. It uses a custom engine with lots of freedom.
I also would have a suggestion for your list which could be quite useful :
Indicate for each game which tool is used.
90% of the patreon games are created with RPGMaker and often revolves about following a story or grinding to get the H content which gets quite boring after the couple first games.
So knowing if a game uses RPGMaker or not could really be useful for players who are looking for something different, like Akabur's games (and mine

) I really enjoy management games (like Simbro) and would like to find more of those but your list is too long and I'm too lazy to check all of those one by one ^^
By the way, there's a small mistake in Gaweb description :
So first, it's Gaweb Studio and second, the main game I'm currently working on is Glassix and is free to download. The game is a mix of simulation and VN. You are free to travel around town, meet new girls and have them do kinky stuff if you train them well enough. My first game was Vampire Revenge and is finished thanks to my patrons help and is only available for patrons indeed. It's an adventure game with turn-based battles and sexual training for the captured enemies. I'm also working on a sequel of this game, named Vampire Revenge Rebirth, which should bring even more freshness with deeper castle management and party management. But I'm still quite early in the dev and have not much to show yet.
