Yeah the guy below pretty much nailed it lol. I'd say this is somewhere around 2.5... so I am selfishly hitting it with a 2 star to average out.
I... guess I personally regret wasting my time on this but someone else may enjoy it. It's an NPC game, AKA women repeat the same lines while being fucked by a sentient MC and becoming increasingly flustered, but still saying the same words and acting oblivious. This game is a bit different than most in that there is only one NPC girl, the mom. I like the idea better than usual, gives some sort of progression to the genre, but it's still just as fucked as any other NPC game.
This particular experience is saved by the two chests outside your home when you leave for the first time. One levels you to lvl99 instantly, the other... idk, didn't try it, I assume it just skips you to the scene room at the end. But yeah the gameplay is shitty RPG-lite-esque turn based combat, run around a map while being pestered by enemies, fight the 3 bosses, fight the final boss, fuck the mom along the way.
Sometimes you come across girls as enemies. Beating them drops their clothes. You can go into your inventory and use the clothes on yourself (dumb UI choice) to initiate a sex scene with mom. Weirdly, you can only have 1 set of each clothing at a time, so there is no use in beating multiple girls until you use the clothes (because they are consumed). But don't worry too much if playing with cheats, the scene room at the end allows a repeate of any mom scene. Sex scenes are multiple still images, sometimes two poses but usually 1, with a few lines of dialog for each image. 1990's era hentai game shit.
So, yeah. There is a detailed review for an extremely simple game. I would not recommend this to anyone personally... unless you have had fun experiences with other NPC games. If so, this is the same shit.
