Lullaby is a large, very detailed and non linear UDMF map with a teal color scheme that takes place in a magic, surrealistic, dream-like world where you must enter a big fortress and defeat all the evil creatures that live in there to be able to escape. I focused on using a lot of bright details, glowy decorations, an animated skybox and even 3D models to add an abstract feel to the map.   Gameplay is a bit challenging (especially on UV), with some slaughtery fights here and there, but there's nothing extremely hard in it. If you're an experienced player, this map should be very easy for you, but if you don't like this kind of gameplay, please try playing on a lower difficulty. A blind run of this map should take between 60 and 75 minutes.   Screenshots:   Information: Port: GZDoom IWAD: Doom 2 Maps: MAP01 (also includes a titlemap and an epilogue map) Single player only Difficulty Settings: Yes Jumping/crouching and freelook are optional, but highly recommended Tested with: GZDoom 4.3.3 and GZDoom 4.5.0   Credits:   Special thanks to Mary Rose, Gaia74 and BluePineapple72 for playtesting the map, and thanks to everyone who supported me since I started working on this project.   DOWNLOAD   If you find any bugs or other kind of problem please let me know.
