A great sequel, improved in many ways and true to the spirit of its predecessor.
A little bit more story but again I didn't really get that into it. Some additional interesting mechanics, a second character in some puzzles, and very cool graphics. Again one level with trippy upside-down walking but it was a bit more understandable to my eyes.
The game says to make sure you have the sound on in the beginning and it is right, the sound design is amazing.
