Nice colorful level design! It was a nice touch to allow for full remapping of keys. It seems like your dialogue system is also working fine based on my conversation with Fiora Flowers, though a QOL improvement might be to allow for skipping forward of dialogue.
I had trouble figuring out what I was supposed to do; there was no clear gameplay loop. I wasn't really able to figure out how to attack. I'm assuming the Godot sprites would eventually be swapped out for non-placeholder enemies! Audio and SFX would also be nice here.
But it does seem like you have some systems in place to allow for a game to be built on (e.g. a working toggleable hotkey bar, a dialogue system, a biome transition system)!
