Sorta correct. People came, then left the next day.
Same when Markiplier did one during the Steam launch.

It's to be expected, people who come in from a Youtuber leave once they stop making videos about the game. 1 video = 1 day worth of playing. There's obviously a handful that stick around for a bit longer, but it's a literal handful.

You wont find more than 20 people still here who came in from those videos.

Mmm, i see. But well, it's better 100 'consistent' players than 1,000 who are leaving the other day. This is what makes this game/community special.
