I'm not a big fan of platformers, but I loved this. I enjoyed the Halloween-ish atmosphere and the state change was fun to play with.
I didn't get to the end because I couldn't find the third lever, it may be on the other side of the small platforms, but I'm the worst a platforming so I can't get there. -_- I did play for nearly forty minutes because it was fun just running around and changing into a ghost. Also I found the secret room entirely by accident.
I do wonder about our character. He reads a sign that says he needs to turn into a ghost to continue and he's just like; 'Yeah, makes sense.' pfft, dude what?
So yeah, I adored this not too many games pull me in enough to continue even when I'm not making progress. 10/10 or rather 5/5. \^0^/
