Hi!!!!! New “BonBon” player here. I found this game from Jacob Geller’s new YouTube video. Came across all of these issues you’re facing as well! I also came across these issues in a game I played a while ago called “Perfect Vermin”. After doing some research on that game, I found that turning off your Wi-Fi, will fix the problem! Not quite sure why, but I turned it off and… what do you know, a working game! This popped into my mind while furiously restarting “Bonbon” for the 19th time, so I went ahead and tried it.
TURNING OFF YOUR WI-FI WILL MOST LIKELY BONBON MAKE WORK ON YOUR PC!!!! (WE USED THE ITCHIO DOWNLOAD, NOT STEAM IF THAT MAKES A DIFFERENCE FYI)
