Many thanks you to and your team for taking the time to play our game and leave reviews! The team agrees that the difficulty ramp on some of the levels made it a little too precise at times, so we do understand what you mean. But we're all very pleased to see you guys hold our game in such high regard :]]
Oops, yeah I know which section you're talking about. I believe the intended method for that section is to time all of your sand to one side before entering and just ride on through without jumping, but judging from this issue being brought up in multiple comments, we definitely should have communicated it better. Thank you so much for your feedback and thanks for playing our game!
