There were actually a lot of instances where unskippable pauses happened that were definitely longer than three seconds. I recorded the scene I was talking about in my earlier comment. The interjection is actually immediately followed by Chive's surprised face, but then it pauses on every character for about 10 seconds:
During the entire video (including the part at the beginning) I was pressing the 'continue' button, and as you can see, it takes a really long time to advance. But it also happened in a lot of other scenes, for example, the two-sprite animation of RJ holding out the Amongus plushie and then hugging it would take like 10-15 seconds in total, every time it was used.
If nobody else complained so far, it's probably just a problem with my PC, although I never had a similar issue with other games. If you still want to try debugging this, I could help if you want me to test a new build or something, I'll join your Discord.
Also glad to have found another Kitboga fan in the wild ;) funny how instantly recognizable that is!
