Nice platforming 👍 That level is brutal on the standard route. The music block jump is doable with some run speed. Or you can do the bullets by running ahead of them and turning back to bounce off. Easy mode if you have a tail - build up speed and fly to the pipe like you mentioned. Then at the bottom of the sub area, build up P speed and do a quick hop before exiting through the pipe. Mario will keep his P flight and you can fly through the rest of the level.
Thank you so very much, I appreciate it. Thank you for the view and I will be picking a different retro game to play level by level after this. Any request?
