Even after reading your comments about scrolling down I had troubles understanding what does that mean (there is no way to scroll anything in the game). But then I suddenly realized that my freewheel mouse just does not work right in the game, and only after locking the wheel it worked.
Not sure why did you add a sword to the game where no enemy would allow you to attack them with a sword.
The most challenging part was to gather all the artifacts (I had to go almost the entire level back both times).
Congrats on finishing the game, though, great job!
