Decent enough. There's 3 sex animations for each of the 3 succubi, with each being a theme. The first is titfucking, the second is oral, the third is thicc ass.
This is one of those "lose to win" games, in that losing means you receive sex, something I personally find stupid, but some people like it. You can also get access to the scenes if you beat each of the boss rooms.
If you want to actually beat the game, just Alt-F4 and reopen if you ever get overpowered by the succubus, as the scene will last at least 1 minute, each bit of text showing on screen stays there for 5 seconds and you can't speed it up at all.
The game itself is a puzzle of sorts. Just move past the room while avoiding the succubus' traps. They appear if you activate a trap and a clicking minigame will begin if they catch you.
Overall, the game shouldn't take more than 1 hour to beat. The animations are very good, but you never see any of the succubi completely naked, only half clothed. No pussy is ever shown and the only tits you really get to see are from the first succ.
I'd give it 3 stars, but it's surprisingly one of the rarer RPG Maker games that isn't a clusterfuck of shit optimization, so that's +1 star.
