While interesting, it is all a bit of the same thing. Try to mix up your maps a little and provide variation so you can use landmarks to navigate, otherwise you just get lost. You also need to package your content correctly.

I do all my maps with the account of all graphic effects. On this map you should see walls poured by light and water patches of light behind a lattice.

P.S. Ill fix files. Thx.
