Right now as far as I know, the only way to get xp is to kill rabits, or other players.
So...if you don't specialize in any of those things, you get tech points supper slow, even at low levels.
I think you should get xp for:
-Cutting down trees, cutting grass, ext (20% chance)
-Slowly over time if your near the waterfall? (once every 1 min maybe?)
-Breaking walls (50% chance)
Maybe also add a shop where you can buy xp for gold?
