Once I got over 1000 I stopped caring about this game. I don't know how, but this game needs to have some aspect added to it to make it more replayable. Maybe the camera zoom-out feature like Astronautical suggested.
Just a few things.
Sometimes the game goes almost completely dark and I do not know why. Is this the spell Darkness? If so that is horribly annoying.
Also sometimes I am moving along and I cannot go further. I do not know if this is a physics thing or a spell being cast on the character by an enemy.
It would be great if this were turned into something more. I like this but you should take this basic idea and develop some story with an actual plot as I would appreciate it more and ignore the occasional glitch.
