I only played a couple of demos before playing Tomba, and really I didn't know what to make of it. In short it's a collection/action game which focuses on action. Which really isn't a bad thing, but what is the fluctuation in difficulty. It can literally go from super easy to almost impossible depending on what part of the game your in. Take the level just before the 1st boss. The wind is blowing hard, there are plants to eat you, and if they catch you will send you back to the beginning. Not to mention you have to land and jump off platforms that is barely big enough for your character to stand upon. After dying about 25 times I gave up.
Try this one if you wish, but I swear it will make you scream.
