Great platformer with a really original idea - I like that you added the ghost lure vials partway through as it added evolution to the gameplay. I also liked the SNES art style and thought the music suited the game well. I did come across a few small bugs such as sometimes not actually dying when a ghost got me or when falling down a pit (though I was able to restart via the pause menu so it wasn't too much of a problem). There was also an issue when on full screen where the black fade-in screen after dying was only a small window in the centre of the screen (so you could see the background around it still).
Really great idea though. Loved how your friends didn't notice after they'd mysteriously changed floors and were happy to go off and dance to music like nothing had happened :')
