Liked the paper visuals and with the story I'm guessing it implies that you're in a book.
Was quite weird how some trees dissapeared in the ghost(ethereal?) world, but have no difference in looks(could have dead trees, or rotten).
The combat could be something more than just touch to switch worlds.
Lack of minimap or something guiding me in some places, made me just wander aimlessly.
Liked the idea of changing the ending depending on who you encounter.
Should probably change the gate collision box so you cant just walk past in the corner(unless it implies that you're cowardly and just slip through the bars?)
Could be made into a interesting and unique game if you decided to expand on it.
Liked it nevertheless.
