No problem! Hopefully you can pinpoint the culprit. If it helps, it feels like the major events objects aren't loaded beforehand, so when the event hits, all the new objects and animations load at once. I assume that would cause a 'hiccup'; and since the screen freezes for a split second, the player basically misses the event (like a jumpscare). I feel like I've seen this behavior in other Godot games but I'm not sure how the engine works behind the scenes; still, there has to be a workaround.
That being said, your first released game is amazing and deserves the attention it's getting! Best of luck with your work ❤️
