Can't say I'm a big fan of gameplay here. The art and atmosphere are very neat but gameplay is not my piece of cake.
At first I tried to figure out the puzzles, but it turns out there is no puzzle with the portals and I jump over all of them to get to the end, not very satisfactory.
Pros:
-Nice music and fitting sound effects
-Nice graphics
Cons:
-Hardly any game-play besides the visuals.
-Not really on spot with the theme as I feel encouraged to just avoid the wierd portals altogether.
