I think this is a matter of humour. I have to see a demo before I get this. Currently there are very good adventures on the market (Jack Keane, Ankh, Book of Unwritten Tales, ...).

Graphically it looks weak and much worse than competition:

The hero has bad shading, too much specularity, simple textures. Environment is very simple. Lighting looks flat.
Probably this is because it is made for Wiiware and PC is only a port.

Here is how competition looks:


And this game is funny also and makes everything like an adventure should do and got excellent scores in magazines.
