The audio is great and the music fits very well. The animation is also fantastic and works well with the atmosphere.
However, I feel the game gets a bit repetitive after a few lumberjacks, I found myself just spamming W which can kill any lumberjack before they could even attack.
I wish there was some kind of combo system to spice up the gameplay. or you can make different fingers do different damage amounts, for example, the ring finger, which hits much quicker than the rest, does 1 damage, while the slow thumb does more.
I also would have liked to see an increase in difficulty after a while. for instance, the enemies have more health or attack quicker.
