TL;DR: Devs asked their Twitter if they wanted to see 150% breast jiggle physics, deleting the tweet and apologizing after some backlash, which in turn got them more backlash from the other side for caving in.
It was rather obviously meant as a joke, so I'm confused about what people were mad at. Did they think they actually intended it to be included in the game? I would've just liked to see that gif, sounds funny af.
It seems pretty clear to me that they definitely intended to include breast jiggle physics at some level, and they decided that that was something that should be decided by the community. That would indicate to most casual readers that it's a priority for the devs. If they didn't realize that would strike a chord with both the pro-sexualization and anti-sexualization people, they weren't thinking at all.
This looks like a cutesy, cozy game that probably shouldn't even have jiggle physics. If they really wanted it in there, they should have just done it and said nothing. The "nasty people" they don't want to "attract" would have appreciated the jiggle, and everyone else would have just ignored it.
The devs brought it into the spotlight and it got talked about. I'm not surprised at that outcome at all.
Probably wasn't clear on that. I meant the 150% thing being a joke, not the jiggle physics. People having a problem with the inclusion of realistic jiggle physics is something that I didn't even consider tbh...
