Well done! I gotta say, "scary and tense" are good adjectives to describe this level! It was never frustrating or overly difficult.
I was actually quite freaked when I saw the first shadow kid, and then when I blindly ran into the Medusa and she killed me. :shocked:
This was a pretty neat dark cave level :D You guys made good use of the different overlays to make the scenario feel mysterious and claustrophobic at times. I also liked the choice of gradients and tilesets, both based on cool colors (blue/green). My only gripe would be the enemy placement on some screens (e.g. the jump on x1005y1011, which relied a bit too much on luck for my tastes), but overall I quite enjoyed it :)
