Stage Select
(X:0->?. The code is correct but the results are a bit buggy. Especially level 3 is unplayable (along with all the stages that have vertical scrolling, if there are any others) if you go there with this code. As for the other stages the problems are much less. When you go to the stage that you want then you'll see immediately the first stage BUT if you walk half a screen the new stage will begin)
