The introductory movie seemed a little murky but in game graphics are sharp.
There are big signs all around the caves (yay, caves!) telling you how to interact with objects and how to jump, but I could see no way to move the character. Pretty frustrating. While rotating the view of the room to see if I was missing something, I accidentally pressed the screen and lo, a big white control dot to move.
As with many ports that use this sort of control, it's a little awkward.
But my character is soooo cute. Off he goes.
