Very cool platformer! I love the setting and the parallax background, however it sometimes interferes with the gameplay. I like the idea of trying not to use the glasses too much as to not anger the ghost.
The parallax effect sometimes moves the platforms from where they actually are, especially when backtracking. The foreground also moves in front of the platforms and obscures the level. You can't jump and use the glasses, which adds a challenge but it's sometimes hard to know if you're landing in the right spot (because the platform visuals move around as I mentioned previously).
All in all very good ideas and implementation, the art is great, it's a shame there is no music and the gameplay is fun!
