The game was fun and easy to get drawn in to and smooth controlls, just the speed of the camera was super fast but i guess that's probably on me with my mouse sense but other than that it was a spectacular game until i jumped up on the table and onto the book and the game went black and didn't respond for 1min and closed itself.
I restarted the game and then it worked to go into the levels, kinda reminds me of mario 64.
I have to agree with other comments, it was a little hard to understand the mechanics, double jump and roll and i also didn't find a goal in the levels, were there one? i just went around grabbing stuff and went back to the entrance. that was also unclear.
