great game! really liked the environment as it feels like a real forest. the sky also adds a lot of charm, especially the night one. its nice to see the different ways you added movement to the scene, makes it very alive.
I have been trying to make a forest scene myself and couldnt get it looking good, I will try to use yours as an inspiration (if you dont mind) and hopefully get a better result.
best of luck if you decide to expand on this idea it is very interesting!
