Just trying to find something to play, so far tried only Cruel Serenade and would be very thankful for any info on other games like that.

GROVE is absolutely awesome, highly reccomend that. Assuming you've played both parts of Cruel Serenade but if you haven't, yeah look for the second title.

Highly recommend timberwoods. It's in the same vain as Grove. Very good anthro based hypno game. However it's not finished.

Altered is a game created by the timberwoods devs. It's a good game with good hypnosis, but I prefer timberwoods.

Hypnothornia is a good anthro hypno game, however also not finished.

Royale Harem is mainly focused on transformation content, however there is a naga who has a hypnosis path so I'll put it here. Royale Harem, while not complete, has been getting consistent updates (at the time of me writing this.)

Perfect Home is a great switch hypno game. You can be completely dominant and fill your mansion with a bunch of hypnotized maids, or you can be a sub and fall under someone else's control. Or you can be both! The game is still being updated, however updates aren't consistent. Thankfully there's more than enough content for you to enjoy.

Perfect Girlfriend is a sequel to Perfect Home, where you play as the Head Maid of Perfect Home. While this game is more sub focused, you can also dominate your fellow subs, if you want to. There are updates to Perfect Girlfriend, however they are also not consistent.

I also agree with Pink, Grove and Cruel Serenade: Gutter Trash are great games. The Cruel Serenade dev is also working on the 3rd game in the series, but that isn't set to release any time soon.

There are probably more, however these are the few that I have played and enjoyed.
