Every vibe coded site is too dark and the text is too small.
It seems to be the "default" style of some models for some reason.
Which makes me wonder if people already experimented with different style suggestions to get different results: "Make it look like an 1998 GeoCities page" / 2005 Facebook / Newgrounds / DeviantArt / HN / one of those Windows XP simulators with built-in window manager / etc
Other than that, great game!
considering free windows being light theme only, it should be a button, not a "system default"
