Adventures of Dino Riki

Even at my best, this game is not one that I'd do well with. It took me a few deaths to get a feel for the power ups and scoring and it is fun and addicting. I really struggled to make it through the first world.
Above is a YouTube video put up by djrellik. Even if you can't get through the game, there is always someone out there who has.
