It's an okay concept, but it's quite rough around the edges. The first thing I noticed was that the 'options' menu seems completely nonfunctional; selecting it didn't do anything. Secondly, the movement is a bit clumsy-feeling, and the UI seems to have mixed up the prompts for the trigger buttons and shoulder buttons, saying to press the former when it's actually the latter. Finally, I got stuck at the place with the steam jets that a previous commenter mentioned, and gave up.
In conclusion, it needs quite a bit of polish.
