Thank you very much for your feedback. I played your game today for quite a while and I think it has a lot of potential. I build a totem, a small house, a few fields, a plow and showel and more. I really like it so far. However It seems to be very complex so I was not able to understand the full game or all of its features.
My feedback: Graphics is very nice, I just would change the player character and the main ground tile, they does not really fit to the rest. Also I would add a fullscreen button and some music or sounds to the game. The upper windows could need an exit button (or should close if you click outside of them maybe). Moving the character with the mouse also could be a nice feature. Also, the "how to play" button is a bit too small. All in all I think It has a lot of potential for improvements, even though it´s already now fun to play.
