Copy pasted from a part of the description of my completion

This level really is great. There were a lot of things that could've made me hate this experience---underestimating the difficulty, arm pain, and a months-long period of inconsistency could've made this whole thing hell. But they just didn't. I still love Tartarus; I love its gameplay, and the satisfying, yet so tight nature of the clicks; I love the balancing, as the inconsistent nature of which turns a far run into an adrenaline-fueled mission to the end of the level; I love the decoration, simple, yet dangerous, jagged and living, ready to kill you whenever you think you're about to come out victorious. Tartarus is one of my favorite levels ever.

Oh where do I begin, this level absolutely destroyed me. When I seriously started grinding this level, all I would do was wake up, play Tartarus, and go to sleep. The level itself is great but keep in mind this level will take over your life if you decide to go for it.
