Thanks for playing and thank you for your feedback.
Screenshots are a good idea and next time I'll spend time on the cover art.
I plan on making different kinds of haunters to help the player ramp up into the mechanics, some less aggressive ghosts to start with. For the geists, if you repel them and they don't have much room to run (<48 pixels) then they will attacked instead of being repelled because they don't like to be cornered.
