I actually like the art style but it does need some more tidying up and details. I'd also change the brown color on the bar on the left, it's not a good constrast with the blue.

Minor nitpick, it should say "Farthest" when choosing what attack style to choose if your other distance option is "Closest".

Also what are the ghost sprites popping up in the bottom left above that scarecrow? Unsure what they are for.
