It took a few tries, but I finished with a high score of 8250 here. Fun concept and gameplay—free all the foxes!
I'd be curious to see how the game would play differently if there were fewer pauses when picking up power ups or completing spells. I think these would be great for a tutorial or when picking up a new item or completing a spell for the first time, but I wanted to keep the action going as I progressed through each stage.
