pretty cool!
i have to say i am not generally a fan of the whole tentacle concept. but this game really sold me on it! i think giving the woman a lot of agency and just dialog in general makes the concept feel a lot more grounded. and, i think making the player the tentacle monster fixes one of the other issues with the kink in general for me: the tentacle monster usually feels completely depersonalized and abstract. but when the player is the monster, well, now we know that we have a personality and an inner world, etc.
one of my favorite moments was when the woman said something like "put me down" after i picked up both her legs. my immediate reaction was to, well, do as she asked... and i think this kind of mechanic really sells that this is a consensual interaction.
so, to elaborate: i think that consent is one of the most interesting ideas in horny video games. usually in video games, the player character imposes their will on the world as they see fit. being asked by the game to relinquish this control is something that horny games do really well. and i think it works especially well here given that the tentacle monster trope is not exactly associated with consent in my mind. but what i like in particular is that it doesn't feel fake. it's easy to say "yeah all the characters in this porn are consenting, as decreed by me, the author," but the interaction with the woman asking me to put her down--this actually sells it to me that it is consensual for real. it is an interaction that can only be told through gameplay, as opposed to dialog, and so it grounds the game, for me.
the tentacle mechanics themselves are fun to play with, and i like the vague puzzle-solving aspects of the game. the way the woman insists she won't open her legs is fun. it feels intrinsically gamey ("let me identify which limbs i need to grab to get to her vagina"), but it's also kinky. it's neat.
