Use the arrow keys to move! When you are on the final level try to dodge the knife. And just a quick tip hold the arrow keys to go and get gears faster.
If anybody got 33 gears without losing a life, please say it in the comments! There will be a slight glitch: If you play the game again and see a rocket at the start, press green flag two times. If you still see it press play and then press green flag. Sorry if this happened to you.
