Use arrow keys to move. Try to get Lucifer the end's spin to 0 and bellow by hitting him. But be careful! doing this will decrease your spin too. Get on the boosters to increase your speed. Going to Lucifer the end combined with Variant Lucifer will knock you out of your place, so it's not that easy, in fact it's actually very hard in my opinion. The game never ends. Click on the flag to restart.
