Finally completed Endless Rain. Fantastic map, but the secret Keeper mystery objective was a massive pain in my ass until I gave up and looked up what I needed to do in a walkthrough. That objective was a little finicky, and a bit of a dent in the overall experience, but still a top tier map. Reminds me a lot of "The Painter's Wife" map in Dark Mod... which, in hindsight, was probably heavily inspired by Skacky's work.
