So to beat Level 11, in Battle Toads, you need to make pixel precision corner turns. Near impossible sounding and feeling. You can however nail every turn. Simply pause the game as you hit the turns. When the toad is no longer attached to his ride you're set to switch the D pad direction to match the next floors direction getting a big speed boost to top it off. Using the Rare Rewind and save features you can guarantee you hit every single turn allowing you to go above and beyond the pace you need to maintain to beat this otherwise grueling level.
