bigger engine update, issues fixed

we’re on the newest Godot 4.0 Beta now, which improves performance issues due to solving a problem in the export i now don’t have to work around anymore, and also we have the fancy effects back i need for the blobs to look nice.

also, since i’m still trying to optimize this a lot (turns out having LOTS of little things colliding with each other all the time isn’t the most efficient physics to calculate), if anyone has an idea how to (efficiently) detect “a blob surrounded by at least X other blobs” for a new mechanic, hit me up on our discord :)
