The concept is really cool here. I love how it slowly reveals its mechanics in a way that's never daunting, and the level design is crafted such that you never lose track of your little orbs. The atmosphere is so well made, a little creepy but mostly just intriguing. My biggest issue is just that it gets a bit tedious. A lot of times I would figure out the solution to a puzzle, only for the mechanical process to involve a lot of walking back and forth across the same paths several times. By the end especially it dragged hard. Everything around it made it still a good time.
