The card flip sound is the same one from a thousand flash games but the pictures, oh man. Misato pressed against a window, tits squished flat like she's trying to escape through the glass. That's the first one I got and honestly it's downhill from there in terms of plot but who cares. The whole thing is just match the pairs, don't screw up too many times or the game gets mad at you. Three mistakes and it's back to the start which is annoying when you're on the last pair and your hand twitches because you're, uh, distracted.
Asuka's there too. The window fog effect is a nice touch, like someone's breathing on the other side. Rei looks completely checked out as usual which is somehow hotter than if she was into it. The art isn't polished, lines are rough, some proportions are... ambitious. Left tit bigger than right tit situation. But that jank gives it this bootleg charm, like finding a doujin in a folder labeled "homework" from 2004. The memory part is basic, 4x4 grid, nothing fancy. I kept clicking the same wrong card because I wasn't paying attention to the card backs and honestly the punishment loop of restarting just meant I got to see the first few images again so is it really punishment.
The Evangelion connection is just the character designs, there's no angels or mechs or anything. Just boobs on glass. The window thing is the whole gimmick. Pressed, smushed, flattened. Someone on the dev team had a very specific thing and I respect the commitment even if by the third round you've seen every variation of "character plus glass equals horny" the human mind can generate. The timer ticks down and I forgot about it completely until the fail screen popped up. That happened twice.
