Really enjoyable game! The level design is intuitive and flowy, and the atmosphere gives me warm Christmas-y vibes. ^-^
My main feedback visually is that some of the tall plants look like spikes. Maybe change the blue a lil' bit so it's less similar to the white?
My main feedback gameplay-wise is that it's too easy to land safely to the side of a spike. It made the level below a piece of cake.
