I love these tags, and the art and sound in these scenes is more than acceptable. Slow-corruption, establishing most of the major characters (aside from the last few girls that get less developement), actual femdom-content and very good voice-acting for the scenes.
However, it's a short, relatively standard-faire game, that doesn't have good mechanics, despite trying to have decent gameplay. The implementation here just isn't that good, and the game does make some pretty bad pitfalls with making the scenes available and interesting in the way they're "supposed" to be played. There isn't a cohesive battle-system here, like there might be in Monster Girl Dreams or MG Quest.
To get in the nitpicks a little bit, the first succubus-boss in the game springs at you without warning the requirement to use magic-attacks to beat her. This would be fine, except that those attacks are gated behind a grind for a high number of randomly-spawning gems, that you need to grind for from repetetive dungeons within a limited time. In other words, unless you have grinded for them, or you know that you have to grind for them (and also know that getting one unlocks useable magic-skills in the first place) then you will likely run into a game-over. All of these are problems that should have been fixed by just giving you a gem after failing the fight once, or letting you buy the gems with money at that point...
The freedom to grind and level also removes most of the pacing from the fights, and kind of forces you to fight the game to get the result you want, instead of just experiencing the game as it is. And that also kinda works against the scenes.
The gallery is probably the best way to play the game, because the scenes are pretty good.
