Play: The button mashing definitely wasn't something I'd expected. I'm always up for a good button masher when it comes to PC games (and only PC games, I don't like wearing out controller buttons but I'm always up to destroy a keyboard) as long as it's not too long. According to other comments, it used to be 40 instead of 25- changing it was a good call, 25 is much more achievable.
Aesthetic: The art is super cute! The girl is drawn really well, and while the main washer sprite is just washer, the one on the end card has so much personality, I adore it. The color scheme is nice, and I agree with the other commenter who mentioned that the grainy sort of filter is very well-done.
Sound: None. (I hope. Otherwise, something on my end is broken...)
Narrative: The washer's one-liners came off more as creepy than anything else to me. If it were longer, it might have started to bother me, but as it is, it doesn't get under my skin too bad.
Horny: Definitely meant to be charged both in imagery- what with the win cutscene- and gameplay- what with the z section.
Kink: It was probably just meant to be silly, but the dialogue felt a little voyeuristic?
Stealth: Not that kind of game.
Harmony: The button mashing works well with the mechanic of washing the clothes. The z section is a little difficult, however, and it feels like it should have just a liiiiiiiil less drain/resistance/whatever.
Novelty: It's a new concept for sure, and I think it works, even if it's not the most serious entry possible.
Final Thoughts: If you wanted to make a longer game, you could maybe have a bunch of characters who live in the same neighborhood or apartment building? That way, it'd make sense that they'd all use the same washer, at a laundromat or the laundry room. Tried LOVE once, couldn't wrap my head around it- mad respect for anyone who can lol. Game thumbnail made me think for a bit that the washer was wearing a chef's hat for some reason.
