A few more level recs

Because I don't have much time, no description, just links (leading to the threads on the old forum, so you should find descriptions and sometimes also screenshots there).

The Oubliette (challenge, short, normal/hard)

Mashu Prapa (environmental/challenge, medium/large, normal)

Temple of the Sun (challenge, medium, normal)

Another Journey (environmental, medium, easy)

A Walk at Night (environmental/challenge, small, normal)

... That's probably enough for one night. :-)
