Thanks for your response. You're a true gamer checking all the holes for secrets, haha. In the first level jumping over the left wall leads to a golden potato and a portal (just before entering the void). In level 2, you can find a portal at the bottom if you dig or jump the right wall and continue on to find the secret level portal. There are other secrets and portals and such to find as well. Potato facts there are about 20.
