This was mainly a test for those ideas :P No bone animation, but lots of smoothing done here and there. I'll leave how exactly for you to figure out with your own testing as a fun treat ;)
Thanks so much for the reply! I'll have to look into smoothing techniques for animation in Godot, as I'm still incredibly new to 2d animation and game dev in general. This gives me a nice hint on how to proceed, and I'm sure it'll be a fun challenge for me to figure out beyond that :)
