Fun game, the controls have a bit of a learning curve to them.
I think I missed 80% of the time I tried to hit something with the special attack button.
When I got vore'd by the crocodile he wouldn't spit me out and nothing happened. I had to pause and select restart each time. He just sat there with that dumb smug look on his face, the bastard.
I used the swapper to find a secret room, so that was cool. Not very useful in battle.
