Overall: 2.5/5 - If you've got time to waste, you might like this, but don't expect too much.
Story: 1/5 - There really isn't a story, just kind of a setup for one. The game just progresses without any real story.
Writing: 4/5 - It's way better than I expected, honestly. Granted, there isn't a lot of writing, but it's not complete garbage like most games on F95.
Renders: 3/5 - The aunt is pretty, but the models kind of look like they're made of rubber. Characters aren't posed into the background very well most of the time and when they are it looks fake, so renders look cheap in that respect.
Animations: 3/5 - some animations are just jerky 2-frame and some are relatively smooth, but the smoother animations also play in extremely short loops.
Sound: 3/5: Sometimes the music is ok but sometimes (like the during stats screen every night), it's horrible. Sound effects are better than averge, though.
Content Quantity: 3/5 - There's a decent amount of content in the game, but the game is pretty short and there are only two characters (MC and aunt).
Content Quality: 3/5 - Scenes are a bit short to be really hot, and only contain one or two poses, but othewise, they're OK. There are quite a few kinks, but without a story, there's no reasoning behind any of them, and that takes away most of the eroticism.
Gameplay: 1/5 - I really hate the gameplay on this game. It's got grind for the sake of grind. Delays making the player view the stat screen for 10 second every game day, and watch a clock for 10 seconds every game day to simulate going to school. Other delays exists too. The only real gameplay is to ensure that you don't increase your stats too fast. You need to go through all of the sunday scenes at each level, to see all of the variants, because you can't go back once you reach the next level. Also, you need to see all of the ecchi scenes before you reach 500 points because the game will end with a final scene once you do, and there's no chance to see any scenes you missed after that.
Bugs: I'm not sure if it's a bug or just poor design, but some scenes don't follow the progression. For example, MC can get to the point where you he can have sex with the aunt, but she still refuses sex in the bath/shower just as if they haven't reached that point of having sex in the relationship.
