The game holds itself really well! the use of the tutorial inside the level is very helpful and the controls are perfectly easy to understand. I think the aesthetic that you are aiming for has a clear vision even though not much of it is added.
I found the jumping mechanics and the bamboo platforms to be rather difficult. Having to land perfectly on the bamboo was annoying and had to reset the save a lot of times (which was really helpful to not get softlocked). I would make the collider of the bamboo a little bit bigger. Not the asset, but the collider. Having a little bit of Coyote Time in platformers for me is a must. Especially when you have such a quick character movement. I won't recommend making the bamboo asset any bigger because bamboos are thin but I love the idea of using them as platforms.
I had no problems with the vines, but I had some issues with the throwing mechanic when aiming high. The seed started to fall really quick, so I had to compensate most of the time. This might be intended on the design. I would suggest maybe using different throwing speeds and weights for the different seeds? Maybe you can create levels where the bamboo plant (being heavier because it's usually aimed at the floor) has to be thrown over a wall. Vines usually go at the top so maybe they don't have much of a curve when throwing them. Otherwise, I had fun with how you approached the different seeds. I think making them really different is a good approach.
Best of luck!
