It seems like a project with lots of love and potential. I love the Pikmin franchise so more of it in new games sounds amazing!
Sadly the build right now is unplayable on my side. I couldn't proceed past the title screen until I plugged a controler. Once the game started, I'm left with no Rolly Polly to use. I'm unsure if I missed something about how to find any at the start, but without any, it's obviously hard to do anything. I'm also unsure being able to walk through the apple was on purpose or not.
In addition, I have huge framerate issues, but that could perhaps be my computer's fault, as I don't have the strongest graphic's card.
Aside from that, I think the univers seems appealing, the aesthetic is pleasant, the menus and UI are clean, the music and sound design are great, and from the little I've seen, some new ideas to push the pikmin formula seem interesting. So I hope you manage to work on those aspects to deliver a great game!
