Thank you! 😄 I'm glad you enjoyed the speed and the boss fights! The easier main route is somewhat intentional — simply reaching the end is meant to be accessible, while getting all three stars, collecting the coins and reaching the upper routes requires much more control over the momentum. That said, you're definitely not the first person to mention the “hold D + Shift” strategy, so it's useful feedback and something I'll keep in mind when designing levels. I really like your description of it as a speed run to the boss room though! Thanks for playing! :)
