I'd never tried an H-game before and had fun with this. Not the greatest platformer in the world, and often more goofy/comical than hot, but the art style and general vibe is charming.
I left a long rambly review but I'm not sure where that goes or if you can see it (I'm new to this site).
Just wanted to echo some criticisms another user gave years ago:
In the sprite sex scenes, the unskippable 'climax three times' routine gets tedious fast when you're trying to quickly get health back and move on.
Also, I really disliked the use of 'aheago face'. Girls don't make that face when they come. Actual O-faces are one of the hottest things in the world, but aheago face looks like a lobotomy. I don't know when that weird cliche appeared in hentai but I wish I could go back in time and stop it... If you find it hot, that's fine, but it will probably put some players off. It spoiled a lot of the sex scenes for me.
Those were my two main criticisms of the sexy side of the game.
