Viral marketing through a r/visualnovels thread where nothing was actually said about what goes on in the vn, horror elements stolen from other VNs, streamerbait bullshit down to having specific programming quirks where it detects of OBS/Xsplit/other recording/streaming software is running and then performs different behavior based on that.
It's the recipe of how to make a popular game in this modern trash world where, according to a fucking Xitter poll that Toby Fox held, that i unfortunately didn't archive or can't find any archives of, there was a 60/40 split between people who actually played Undertale, and people who just watched a fucking streamer/LPer play it.
