Not really surprising in the end. The price and that artstyle on the game's title card likely turned off a ton of people. Fair or not, people see the schoolgirl aesthetic and immediately think it's a sleezy porn game due to how many of them flooded in after Valve opened the floodgates.
I totally get why a lot of people wouldn't want it, but this is way too low. Even lower than Xanadu Next.
