Important Controls
To navigate the World Menu, use <- and -> keys and space to select a level. A black circle means the level unavailable, red means you can select it, light red is a transition zone, and yellow means special content (Used in the end game). You can also always use the Enter key ingame to go back to the World Menu. Move using A, <-, D, ->, and use Space for jumping. To use buttons, jump on them. You may need to walk around the top to activate them. Levers, and ladders are activated by standing near them and pressing up. Cars automatically move forward. In a car level, all you need to do is jump.
Please Note This game should automatically save which levels you have completed. If you have issues with certain things or the whole game is not loading in correctly (Random objects might appear like red squares) it should be ok to reload the page and try again.
