@DasND The levels of the original campaign are, indeed, impossible to find through the search function. That's why it says that you need to find the right server in the instructions. If you had looked at the instructions instead of asking someone about it right away, you would have found the right level within a minute.
It is great how this game provides a blend of different concepts.
All levels are player-made, and you can clearly see how things work.
There is a wide variety of levels to choose from, to suit what you like. Art, traps, racing, stories, or even exploiting the quirky bugs - you can find nearly everything here.
The game also gets updated often, by someone who really does listen to the community, and does everything to improve the game.
This game has been one of my favorites for years, and it will remain so for a long time.
Upgrade of "ShadakScartans" comment. Doing extra tricks like Up and Out to create a combo can double, tripple, quadrupple (and possibly even more) your trick score.
Certain hats will make you fall when hidden and an avalanche hits you in the second climbing training, because they are too big. + to make sure the developer sees it.
Strange. In the flying exercise I kept pressing up when I almost stopped, and I turned upside down and started to fly backwards. I didn't know ducks can do that.
What really strikes me, is that the cat actually smiles all the time. That's all he does, besides eating. HE SMILES. You throw him against all kinds of walls, moving wooden planks, and he actually seems to like it. O_o
