This is the second version of my Half-Life mod, it has 8 maps to explore(not including the Selection Hub). Every new version of this mod will add at least 4 more maps to the game. This game is heavily inspired by games like LSD Dream Emulator and Yume Nikki.
The song in the video is "Born Slippy" by Underworld.
The crazy visual effects aren't in the mod of course.
