I ddeply enjoyed this game. Reminded me of the old "Darkness Falls" games that used to be on this site. A lot more focus on mind control and moral corruption than just physical transformation.

The best part (for me) is that the M/M content is acutally M/M content and not part of the M2F content, which is a rarity on this site.

Awesome game! Somewhat reminescent of the Darkness Falls series

You might want to skip some of the characters if you're not into m/m or futa stuff but it's pretty obvious wich ones.

I've enjoyed the previous versions of this game very much.  This version as soon as I went to decompress it the .exe file was removed by my antivirus and identified as Heuristic.

Really solid, one of the best of its kind in the genre of games where you influence and change other characters. 


Haven't gotten far yet, but what I've seen at this point is already great! I think the final product is going to be awesome.

A surprisingly engaging puzzle game. It's sexy, particularly if you like mental transformations, but certainly not a fapfest. Can't wait for the next update!
