Really like the art for this. The concept of "charging" up the shovel was pretty fun, especially once I realized the character would charge towards where I released my mouse.
I think it would have served the game well to keep score of how many ghosts you killed (and larger points for the bigger ghosts). I also think it would be nice if ghosts couldn't spawn right on top of you - it felt like some hits I could do nothing to avoid.
Really pleasant little game, and gets me exciting for Halloween season!
