That was fun ! And astoundingly pretty ! I thought the idea was super interesting and polished nicely, especially with the randomness of it, it didn't feel unfair, but it wasn't easy either.
I miscounted the sheep a couple times, as it turns out having my attention on the two things going on at once was tricky, but I liked that ! I didn't have to turn the light back on once though, so i don't know what that does.
I'm also easily frightened, so that kinda made the adrenaline pump, with the creepy noises, color choices and sense of impending doom ! Good job !
