So the gameplay is exceedingly simple, but also exceedingly grindy, boring, and repetitious. Also, while breeding is obviously the main focus, pregnancy is not a focus at all. Once you get a girl pregnant, the baby is immediately born and you can breed that character again.
There are a few screens showing a morphed view of the pregnant girl, and then everything goes back to normal, so if you're here for pregnant ladies, don't bother as it's all about the breeding, and not about the pregnancy.
The tutorial is definitely worth going through as it teaches the most essential function, which is how to completely destroy the "rival" just by shooting him a little bit every now and then since he has 15 health, but can only challenge you to a fuck when he is at full health and it only costs like, 1000 yen to shoot him once.
Honestly, not even sure why he was even implemented, because he is horribly irrelevant from the get go.
The art is definitely sub par, feeling like something that was made for a flash game in the early 00s by an artist who has a fetish for folds. You know, the kind of stuff you'll see if you spend a little too long on Pixiv.
It IS fappable if you are desperate, but it boils down to just standard flash game mechanics where you pick a pose with the main girls, go through some different speeds, and then cum inside or outside depending on how full the bar is when you click, which seems like an unnecessary addition considering the goal of the game is to breed all the women.
I would suggest avoiding fullscreen mode if you use multiple monitors though as it just stretches the images to fit the screen and does the thing where it will cycle all of your monitors, so if you have other windows open on a separate screen, prepare to fix everything.
It's not the worst game I have ever played, and it's better than quite a few games on here that get way too many high scores, and unlike some of the highest reviewed games on here, this one can at least say that it is complete without being in development for a decade.
