I ask because of rabbits will give you a reward of +1 xp.
That makes the bow currently a lot better than the axe to level up in the early game.
Could you add more xp-bonus for using tools like axe (trees), breaking stones, cutting grass, eating mushrooms,...?
Maybe think about keeping the ratio of time/xp the same.
I guess trees will take longer to cut compared to rabbits to kill and therefore might should cause you a reward of 2-3xp.
