I can also confirm it works fine in window mode.
Both outfits freeze on full screen although the left outfit freezes a couple of seconds earlier for some reason.
It's kind of hilarious that after all the delays there's a game freezing bug when using fullscreen literally not even more than a minute into the game.
How does something like that even go unnoticed? Did no one test fullscreen mode? Well the engine always had more issues in fullscreen than windowed from what I remember with School Days.
Hopefully this can be patched asap as window mode is too small for me to enjoy and hopefully the anonymous uncensor patch comes out soon too.
