Getting frozen sometimes happens due to RPG Maker Unite bug. It's strange because just fidgetting around makes you able to move again and sometimes not. (You can see this actually in a let's play of the game, fidgetting especially with mouse solves the issue) Again, RPG Maker Unite bug and sadly not something I can fix. Fortunately it only occurs if you take the wrong route and not always, but it's a very weird bug.
The font and volume being too loud are a Unite bug. (I've already lowered the volume how high the sounds play!) The bartender changing apperance is oversight on my part, but I can't fix it right now.
Yes, it's like Lost Woods in that you have to go in certain order to pass. If you want, I can tell you the spoiler for the correct route. Only the final branch near where you heart the chime or buzzer is the one that matters.
