Very nice.
The artwork is spot on and the music fits very well. Story is basic but very well told.
The choice of having no text was worth it as the story pretty much tells itself and is clear enough, it also gave it something 'sweet' for me as a result. The puzzles were intuitive and easy to figure out,
I wish it wasn't over so quick - which def is a good thing xD
As far as issues : only the lag can get bad at times (especially on that one map).
other then that I am impressed :)
