An exhaustive trawl of my porn game storage would be.. exhausting. Even I don't recognize everything in there; sometimes I find good stuff I'd never even unziped, and a lot of the japanese origin stuff is only labeled by their DL site #. I actually found LIVE_HAISHIN.ISO while I was looking for this stuff, which I'd never unzipped, installed, or played. But these were the small ones with train molestation I saw from the last year or so:
JK Molester Train Seeding Uncle - played it now, pretty decent small-mid sized game. First 5 or so days you get nowhere then all of a sudden everything is unlocked
I_strayed_into_the_women-only_carriages - tiny game, but decent pixel art. The dev, pH studios, has several other games
Erotic train - no real story, just pixel art fucking on a train
JK Molester Train VR - weird interface, ok almost mid-sized game, no real story
The Corrupting Train Feel-Up of a Strong-Willed Girl - Tiny game, like really tiny
(同人ゲーム) [2020-10-03][RJ282536][同人美少女ゲーム] 通学バスで痴漢防止の為、露出させられているギャル少女を痴漢する!~オナニー用ミニゲーム - also a super tiny game, and I don't think it's on F95zone since I'm pretty sure it's untranslated. The dev, girlsgame, has a number of other extremely tiny games
I know I played another recently but just cannot come up with the name; it doesn't seem to be in my folders but if I remember it I'll post it. If you're looking for tiny porn games though flash is still amazing; just download games from swfchan and play them on a standalone flash player. Standalone flash players are easy enough to look up if you don't have one but I attached the most modern one I know of to this post.
