Use Glitches to your advantage, I don't care. As long as you're succesful. Use Shift to zoom out. You can roll barrels, press buttons with them, and jump on them. Slime is not a fully one block. Purple charges can be moved by slime, you, and other charges. Small balls of slime send signals. The fire transit breaks if it so much as touches magma. It is resistant to fires though. If something goes wrong, you can either reload the page, restart the level by pressing R, or go into the editor. But Don't change anything to make it easier, or you will be a loser.
