It's an adventure game disguising itself as a platformer.
You can pick up items, use them, interact with objects, there's even a scavenger hunt. And the game certainly has no shortage of puzzles and other non-twitch problems to solve.
Like I said, it's difficult to find. I looked in three stores and they all told me it was out of publication and they weren't likely to recieve any new stock soon, so I felt justified in aquiring it by other means. I feel bad, because the developers certainly deserve the money and would use it to finance their next game, so I'll probably look to buy it on Ebay soon.
