I renamed all of the worlds in Vampiric Tower Remix. Medusa's Lair is called "Dimensional Prison" (Episode 3, World 1) in Vampiric Tower 2.
In fact, here's a list of the name changes!
The Old Tower <-> Foyer of the Gods
Jiangshi Junction <-> The Crypt
Faerie Gardens <-> In the Peristyle
Magick Library <-> The Duchess's Archives
Tomb of the Sun <-> Vaults of Montezuma
Bodacious Botany <-> Gardens of Venus
Medusa's Lair <-> Dimensional Prison
Atlantean Shrine <-> Sunken Shrine
Lil' Bot Factory <-> The Far Future
Ethereal Palace <-> Frozen Peak
World Tree Roots <-> Yggdrasil's Appendix
The Pearly Gates <-> Heaven
Awesome Alchemy <-> Alchemy Lab
All Hail Mars <-> Temple of Mars
The Grand Finale <-> The Apogee
