This is the first entry I've seen using the monochrome one and it's very fitting I think. I reaaaaally hate the music though, sorry - it's like three notes that keep repeating and it's very off putting :D A toggle would've been nice :D
I really like the mechanic that stuff only appears once you get close and I love that you can investigate almost everything. It's a really creative approach and I would love to see a more fleshed out version of that mechanic!
