Funny game. At this point, though, the dog is very slow compared to the ghosts, and overall a weak attacker. As far as I've seen, dashing is the only way to get rid of ghosts, as barking doesn't drive them away any significant distance and the movement is slow. Combined with how slow it is to charge up a dash, I was quickly overwhelmed.
Love the premise, though, and I'd love to watch it grow over time!
