Really glad you enjoyed the gameplay! The "loop" happens when you get to the very top of the level, as the setting is an hourglass (it's not fully clear but that's why there's sand rising) you now have to redo the level but everything is flipped, I focused too much on making content that I made the level too hard and too big for most people to see the "loop" lol (and hence the lack of polish in many areas), glad you enjoyed the concept even without seeing the loop part!
