Fun little game. My biggest issue is that it seems too easy to keep axe damage high enough to chop down the current level of tree in one hit, which made the critical and multi-hits seem useless.
Early game definitely is too easy to one hit trees, making critical and multi-hits. I've noticed most players only level these skills up, once they reach the mid-late game.
I've added this to the backlog of balancing the progression of the game.
