TLDR as of .009: It's REALLY good, but don't play it. I can't give it any less than 5 stars since that would be an utter lie, but I 100% cannot recommend anyone to play this game yet.
Everything about this game is amazing. Art, Dialogue, the Sandbox, the Corruption, the progressively skimpier clothing, etc. However, I can't recommend this game simply because the rate of it's growth and the scale of what the game wants to do. As of right now, there are 5 "doors" in your inn/hotel, which implies 5 girls to live with, and from the pattern that we've seen, all from different universes. As of right now, there are 3 girls, and 2 "complete" stories for the girls, and it seems as if each girl will be able to "recruit" other girls from their universes (so a total of 10 girls). There also seems to be a plan set for multiple clothing items with different variations, multiple attractions, etc. However, this game gets updated around once every few months, and the updates only provide average-sized to small-sized content. I remember seeing this come out as version .001, and decided to let it cook in the oven. Now it's at version .009, and I got around 4 fun hours, but considering how long this game has been cooking, it seems as though what I got was very small.
So, if you're interested in this game, come back in 5 years. It'll be good then. If you decide to play this game anyhow, then you'll feel dissatisfied for every single update that comes up for years to come.
