Hi, thx a bunch for your comment :)
* spoilers below *
I am going to SPOIL some things that you can achieve: there is a fixed amount of seeds in each layer. Growing flowers from these seeds makes markers in the sky light up, so you could try getting all of the seeds and reading all the notes. Another goal to strive for is finding the glasses which allow you to switch into a screenshot mode. To get the chest at the bottom you need another item (found higher up).
My personal definition of 100% is all seeds, notes glasses chest. But tbh I think it's unrealistic to expect getting everything, you've reached your personal 100% when you feel no need to play further (;
Oh, and a basic thing that players sometimes miss is the ability to create a crossing in a spot of choice after every grown seed (aka using your charge).

Thanks! This helps, I was indeed figuring that I need to get all things and seeds, just wasn't sure. Have found all items except the one for the rocks, so I'll have another go probably. It's not about the goal completely, the experience itself is also nice! I did read the note that mentioned how to make crossings indeed. Also found out the teleport option.
Well, you don't need to achieve anything and there is no in-game fanfare for getting 100%. I've definitely found myself hunting for completion anyways and it's doable with some luck, but I don't think it's more fun than the first few explorations and discovering how the vine works. Then again I can't really explore or discover my own game so what do I know :D
