I really liked how you interpreted the theme.Intruduction part was great and i loved the character sprite(Eye of the Sauron lol).
My issues are there is no background music maybe adding a simple music can help?
Adding a pause menu can really help the game i was frustrated at the giant saw part and wanted to pause to calm down but got repetadly killed :D.
Other than these complaints i think you made an original fun game :D Great work
