Looks great! Only thing I'm a bit weary of is the ghost coming after you, as I hate timers in games! Is it a timer thing or is it just random? How do you defeat it? (If you even can).
Glad you like it! The ghost appears randomly only when you take a chest. It disappears after 30 seconds or if you activate the invisibility spell by pressing I and running into it - that grants you 250 points.
