Very nice graphics and music!
Some feedback on the gameplay: there were instances where the monster was very close behind me but couldn't reach me, but then would catch me even if I did the next obstacle right (I saw the wall get destroyed so I think it was right). Maybe there is a slight unintended slow down during the obstacle animations, or maybe it is intended that the player slows down on each obstacle, but it felt a little unfair to lose even though the input was correct and on time.
Other than that, it's a fun game. Well done!
Also, just noticed that you can press shift + d at the same time to deal with both obstacles (the floating tree and the wall). :)
