It's called Hentai Devil Memory Photobook and right away the title is doing too much, like someone couldn't decide between three different porn games and just mashed them together. The premise is simple, a memory card matching thing but with anime tiddies as the reward. You flip tiles, find pairs, and the girls get more naked. Standard stuff for browser hentai but the devil theme is barely there, just some red skin on one character and horns that look like they were drawn in MS Paint by a horny teenager during computer class.
The nudity progression is weirdly paced. Easy mode gives you basically softcore ecchi, panty shots and boob windows, but then hard mode jumps straight to spread pussy and ahegao faces without any real buildup. It's like the artist got bored halfway through and just started cranking out the explicit stuff. The parody tag is doing heavy lifting here because I recognize exactly zero of these "devil girls" from any actual anime. They're generic big titty demon OCs with the same face syndrome, different hair colors slapped on like palette swaps in a fighting game. One of them has wings that clip through her own shoulders in the final nude reveal and I laughed out loud, which I don't think was the intended reaction for a hentai game.
The memory mechanic itself is functional but barebones. No timer, no score tracking, no unlockable gallery after you finish a level which feels like a missed opportunity. You complete hard mode and the game just... sits there. No fanfare, no "congratulations you pervert" screen, nothing. The card flip animation has this slight delay that made me think my browser was crashing the first time. Works fine on mobile though, played it on my phone during a boring Zoom call and the touch controls are responsive enough. Wish there was a way to replay individual girls instead of redoing entire levels but that's probably asking too much from a free browser game that exists purely to get someone's Patreon subscribers. The photobook part of the title implies some kind of collection system but it's literally just the cards you already saw during gameplay, no extra poses or variations. False advertising if we're being honest but also who's filing complaints about hentai memory games.
