I take that the game has two levels? At least when I completed the second one, I got back to menu.
Anyway, it has been pretty fun walking around and trying to get the enemies into the shadow of the attack blocks (or the shadow shield). Took me a bit of figuring out how things work, but once I did it has been pretty nice. That said, casting the Solidify/Illuminate spells felt a bit clunky, so I preferred to walk around and get the ghosts into block shadows instead.
Nicely done, overall. ^^
