From what I can tell so far, the game seems like it has a lot of work put into it and has a lot of depth. The graphics are pleasing and the sound effects are nice. The crafting and inventory system is also well done.
Minor tweak I would suggest is allowing you to hold down the arrow key to move.
Unfortunately the tutorial is incredible bare-bones and none of the items are labeled, so I had no idea how to work with the game. I managed to craft some railroads and a black blob thing, but I had no idea what to do with them. Also, placing seeds from my inventory didn't seem to work when I left or right clicked on the ground. I'd say it looks like you have a a good game but it's impossible to explore unless things are better explained.
