I had some trouble with the movement at the beginning. The boost rings didn't make much sense at first but after 10 minutes or so I was able to get past the first island. The second one I found much harder than that but eventually got it. However I fell off the third one and since there is no death trigger I would have had to repeat the first two islands, so I stopped there.
I love the aesthetic. It reminds me a bit of a short hike, but it still has its own charm. The little movements the leaf makes are fun and the wind sound is fitting. Only thing I would have appreciated would have been a fullscreen option.
