Generic clicker. As far as gameplay, there isn't anything interesting here. You can switch between characters but you're basically starting over from scratch when you switch to a new one. No upgrades or decision making involved. Each passive "upgrade" is a new scene, but they are literally just 10x the prior one for the price and earnings. Idle earnings are so minimal that it's just...not a thing. I left it idle for a full day and only had enough to buy 1 of the upgrades that I already had.
There's a ton of art but it's AI generated and a lot of it is very similar. There's nothing to distinguish the characters in terms of kinks or mechanics, except the ones that pair 2 of the characters which includes some lesbian/threesome stuff. From what I could see even the images that involved cosplay outfits were the same for all the characters.
Art is nice, but it's AI generated and a lot of them are just small variations between images. If you hid the faces/hair I'm not sure I'd be able to distinguish between them.
...Yeah, you might as well just go find an image board if you just want MHA porn. If you REALLY want to grind these out, I found the best approach is to just buy 10-12 of the best one you can afford, and then save up for the next one. No reason to bother revisiting and buying more of the older ones.
