This is a very good start.
It is one of those rare cases where person who makes porn game doesn't forget to make an actual game (you can unironically play this for more than porn).
Gameplay wise i can see how someone would accuse this one of being too repetitive, but if you can stomach roguelikes this one is more than fine.
Difficulty is fun, as in: it is hard but doesn't feel too unfair and forces you to actually engage with the game.
Art is amazing.
Porn is good but there are some caveats. Obviously it is a demo so there isn't that much of it, not a fault of a game, but it still important thing to mention. Also unfortunatly as of right now (from my understanding) main way of seeing erotic stuff is loosing the game (i personally don't mind, but i can see how someone would be disappointed).
