It's a nice little game. It creates a cozy atmosphere, the art style, the music and how everything is composited together is coherent. It is pretty intuitive how it works too, and hex-tiles are always a nice approach to such games. My only critique would be regarding the gameplay loop as-is; because there isn't really any "resource management" to it. You're in spring, spread the trees to the next tile and add 1 resource to that new tree (so investing 2 resources / 3 if not a grass tile yet), and then spam-click change season until the tree is fully grown. Repeat until game is over) Fully-grown trees seem completely self-sustaining (or not even able to die at all), so in spring you can just use up all resources you have to spread out. (also I'm not sure what is supposed to happen at the end of the game, for me it just turns black and nothing happens anymore, I assumed it should loop back to the starting phase)
Nonetheless a very well polished cozy game, and with a bit more depth and variety to the resource-management gameplay-loop, it could be something pretty cool to play!
