I'm not sure if this has happened before, I've no interest in scrolling through pages looking to see if it has, but for me, the entire game freezes after choosing the smoking preference and you see the MC's (presumably) ass. nothing but ESC does anything, not that any of the ESC options help.
Played a lot of games on here, but this is the first where I've come across a bug before even getting into the game. I assume the developers have some reason they are using Unity, preference, or perhaps just what they are versed in, but I also assume a big part of their motivation when creating this game is Patreon pledges and money. I've never had an issue with Ren'py games other than the occasional missing file, but you always get the option to ignore and move on. I don't know if this is a Unity thing or not, but it just irritated me since I waited for this to download just to encounter a bug right out the box. Deleted it now and will move on, but if this goes to another chapter, the developers should look into migrating to Ren'py, which will no doubt mean more people will be able to enjoy their content in a familiar and easy to use way, and in turn,p will result in more pledges.
Just my 2 pence anyway.
