The voice acting is well done, and the fact that you can pet a cat is obviously a plus.
I think the second level may be too big: you just go straight into the caves, which are big and empty, with little variation. The best level by far is the last one, which is very colorful, with a more interesting level design and a far-reaching field of vision!
I had a few technical problems with the mouse losing focus, but apart from that, the game runs pretty smoothly!
