Thank you so much for your feedback! It's something we've heard a lot. We currently have a character who wants speed and a level design that wants precision. We're reworking the levels to focus on speed.
And as for where you got stuck, the level's intention is to encourage you to gain speed with the last stretch of diagonal platforms. They usually have a marker to indicate where to jump.
Sorry if that wasn't clear :( we will work on it too <3.
