Thanks! The difference between Walk1 Walk1 and Walk2 is that you can the first one gives you two tasks you can finish while the second one can only be finished once. And the reason it can go to Walk 0 is that whenever you walk, only the top most fulfilled task gets completed and counted. So a Walk0 is basically a free step you now have left over. (If I continue working on this I'll try to make all of that more obvious in the game itself)
