I'd rate it a 2.5 instead of a 2 if I could. Ultimately it's just okay.
It's dollar store slay the spire featuring some in battle sex. There seem to be a small number of special sex scene, but otherwise it's mostly lower detail sprite animations and text. The combat isn't particularly good and the random encounters are dull. The cast of succubi/monster girls are the most generic possible choices imaginable.
Unbelievably, it's actually retailing for more than Slay the Spire on Steam. This game is not worth 10$. Considering the low amount of meaningful content and not great game balancing, I'd say it's worth about 2-4 dollars at most. If you just want to pirate it for a quick fap to generic succubi H content, go for it.
Small warning. Your character actually outright dies via being raped to death by the enemies. Put a bit of a bad taste in my mouth, so maybe avoid this is that would be a big deal to you.
