I haven't managed to beat it yet, but this is swag (as the kids say). I really like the adaptive music and the extra-depressing feature of being forced to continue undoing your work until you reach a wall. Side thought: how on earth did two people with "kelp" in their username end up incorporating feathers?
Update: Having ascended, I am now smugly mocking all the poor souls who lack the skill to ascend. Now if I could just make my hands stop shaking...
