First:
Princess Knight Rose. Should be in this thread if it's not already. Very uh, unique art, but if you can get past that there's loads of permanent status effects; some have graphical changes, some just affect scene text. Heavily focused on multiple orgasms and "intense" orgasms. Not sure how good the MTL is. Almost entirely combat-less and has a ton of text. About 1-2 hours long - longer if you want to go through every ending. May also fit on the list in the quote below, I don't remember.
Now, a few additions for this hypno/MC games list, with a couple that fit in this thread or are in this thread:
I thought this was in this thread but I can't find it:
Ayura Crisis! is an absolutely fantastic game from a new developer who is now working on a second game. Side scrolling action game with a few enemies that MC you - maybe more, I don't remember. There's at least one temporary transformation and loads of permanent status debuffs that usually make you more susceptible to H attacks.
Mentioned earlier in this thread, I'd recommend
Trap Quest - has a few MC/hypnosis (booby) traps, and some other MC content, along with a lot more general corruption themes. Note that the F95 thread doesn't always have the most up-to-date version and isn't actually necessary unless the unlock file is out of date (changes about twice a year) or you love to use the clothing window. Check the official website for the most recent updates.
One more from this thread:
Star Knightess Aura, while very early in development, is almost entirely focused on MC, corruption, etc. Slow progression but very on theme. Seems to be updating frequently.
Reimu Gets Brainwashed. You may have guessed from the title, but this game is about Reimu (from Touhou Project) getting brainwashed. I have not played it but the CG (on panda site) looks quite good - "VR helmet" style MC/hypnosis. The version I linked is from F95 and is an MTL with text overflow; I'd recommend just finding a Japanese version and using the usual clipboard based translation tools, honestly.
These last two games from earlier in this thread are from the same developer as B-Ground Unchained. I don't think either of them has a translation, sadly - that or I just don't know where to find it. First game is the Exorcism show one. Very unusual gameplay mechanics but has several permanent MC statuses inflicted by the various ghost/monster enemies. There's checkpoints you can restart from once you get to them and you can toggle things if you want to carry them over when you restart. Second game is Drifter Rei. If I remember correctly, two of the (6?ish) sections of the game are mind control / hypnosis themed. Neither game is available in its latest update except from very slow DLs on a-s, as far as I know. Somebody should do something about that.
