Use cursor keys to move Jr. Muncher through the grid. Pressing a key once is enough for continuous running. Hitting a key in advance one can even steer into a junction before having reached it, hence navigate much quicker. Please go sure the Scratch panel has the input focus (you may have to click it once after game start) Created for ToyToy Games. Put in Turbo Mode for Impossible Mode.
I don't need to give credit to myself, so I will say @ArnoHu for now. Also, JR. MUNCHER is made by ToyToy Games Inc. Copyright 2016. Fun Fax: Put in a little secret you might enjoy. In the 1st second of the project, hold down the "L" button. This will cause the game to open a level select screen. (see bottom of project)
