I built two tiny helper tools to speed up fine-tuning hitboxes and sprite position offsets.
Both editors using HTML this was the quickest way to implement it.
The Hitbox Editor let Me upload a spritesheet and draw a rectangle where I want the hitbox to be.
Same goes for for the Sprite position offset editor, that i made for the elemental whips because they all have different reach and needs different positioning.
This will be useful for other sprites as well, before I did it manually in Aseprite Editor or even in-game using debug functions, but both was a lot more time-consuming and not as nice as these two editors.
I might expand the hitbox editor to support other shapes than rectangles, if required later on.
