I don't think assets need to be centered. Usually engines will let you choose the center point. Anyway glad its work for you!

You can indeed change the center point, but it doesn't help when flipping the sprite. Here's an example : I offset the center by 4 pixel, and then do a flip. Unless you define regions manually for all sprites this issue will always happen (or if you offset the whole spritesheet by 4 px which I did myself)

In Godot, the origin point is mainly used for Y-Sorting, flipping only flips using the texture's width / height . But yes, you can use code to flip the texture and then move it a few pixels in the X axis, but it would've been better if the sprite was already centered. Anyways, I fixed it really easily so no worries about it :)
