There's a big ole update coming sometime this week with buildable objects and tile editor I believe. In the meantime they've put in:

• Choppable trees (only ones you own)
• Gatherable objects (can take from any tile): flowers, stones, carrots.

There was even a fun contest for carrot gathering and wood chopping. I placed in both and got like 0.19 ETH worth of gold for the effort :)
