I'll try and drop back round once I get through the list of games I wanted to rate and give it another go so I can give a clearer idea. From what I remember there were sections where I wasn't really given a direction (lie or otherwise) and just had to trial and error it out, but then that branched into more and more trial and errors. I suspect I lost the "intended path" at some point and was ending up skipping certain parts and ending up on a route I had missed the directions for.
EDIT (in case you miss the discord message): I watched your youtube video and it reveals the problem I encountered - I had no idea mushrooms were supposed to bounce you, I somehow skipped unlocking that and got quite a bit further into the game... there is a section where you have lots of tall vertical areas you are supposed to bounce in and out of but I only had wall jump to navigate at this point.
