I'm starting to try my new game on other android devices than my own and I'm very disappointed with the performance. What I think is a simple 2D game is struggling with stuttering and low fps.
Since it's my first Godot game, I'm assuming it's due to poor programming choices and general ignorance towards Godot development, so I'm going to rewrite whatever I can to make it better, but I don't know yet what makes it "better".
So I'm asking this (and I've read the previous questions about this subject) hoping to get some guidance relating specific things, like "tweens, are they expensive?", "resizing sprites, does it have real impact or is ti marginal?", what are the usual fps killers? Are there instructions to avoid?
All and any advice is welcome.
