I like this as a relaxed and slight goal-oriented toy; the aesthetic changes from each tree are pleasant and the gameplay loop being previsible with just a little bit of randomness to it feels just right for a game about growing a tree
More punctual feedback:
- more variety in branch shapes would be interesting
- leaves disappearing when they collect light seems a bit odd; I imagine this exists to avoid endless farming of sunlight/moonbeams, but that could instead be done with the leaves withering over time instead
- a volume control for the music would be nice, it is a bit loud on my PC; the music if very pleasant, though
- the text gets impossible to read during the night stages
