Wow! This was really good level design and obstacle design, first of all. But in terms of the Theme, I loved how in each level you introduced another element of the lyrics from Running Up That Hill. First we're running, then we're fighting to survive, then we're climbing up that building, etc. The attack and movement mechanics could have been a bit tighter. Sometimes it seemed like I froze up and couldn't move but there wasn't seemingly a cause, and sometimes I felt my attacks were not as responsive as I would have liked. But, I felt like the enemies I needed to attack represented a fair challenge given what I had to fight them with. I think my favorite section was lvl 3 in terms of how the controls felt, and the final level was a nice challenge with the timing and placement of the arrows relative to the hill.
