Bright lord
Shut up and dance
Shattered minds
My best deal
Claiming people haven't played good mind control avns and then giving this list. Now I haven't played Bright Lord, so I will refrain to talk about that, but Shut Up and Dance wouldn't be classified as a good MIND CONTROL avn in my book. While in the beginning it does seem like the mind control will take center stage, it is downplayed for most of the game and something that gets mentioned in the reviews somewhat frequently. A good game, but not if you are looking for the mind control/corruption aspect of it.
My Best Deal is a bit better in that regard, the MC does use his powers more, but not as much as this. Your choices are greater here in the moment, but it is still early game, so it can be difficult to see how it will pan out.
Shattered Minds I agree with. It is currently my favorite game on this site. The mind control aspect is very central to the story and the love interests. The focus is on getting a big harem rather than further developing a few LI's, so it can be a negative in that regard if you prefer fewer, more well developed characters over many. That being said, I do feel like the characters are fleshed out, it is just that they mean little once their stories are over.
Personally I would point out:
Mind Society, which although in a somewhat limbo is great with a good focus on mind control
My Hypnotized Family
Snow Daze - A completed game, not that long, but great
Summer MC
The Gift Reloaded. Abandoned, but still has some good mind control elements and quite some length to it, but ends in a cliffhanger.
