The game was really pretty, you did a great job with the sky! Especially how the stars twinkle faster when you move. It was a nice touch.
The game was cool, though I think there is something wrong either with the raycasting or the collider on the trees because it doesn't always harvest properly. Also, it would be much nicer to have a playable tutorial than a lot of text at first. It took a bit, but I kind of got the hang of it. Nicely done!
