Diamond Rush Perfect Walkthrough: Bavaria Secret Stage 3

There is a glitch in this stage, at least in my version of the game, 1.0.3 (you can check your version choosing "about" in the menu). I guess the glitch is related to collision detection (which seems to be tile-based). You can see the glitch at 1:35 and 2:13. The character keeps trying to climb up (because I was pressing the up key), but the game blocks the move. You can check (by advancing frame by frame) that I waited a complete retreat from the spike before trying to move. I nailed it at 2:50. Using the checkpoint seemed to help, but maybe I just waited a little longer before moving. There is little room for error, the spike advances into that critical tile as soon as I leave it. I strongly suggest you don&mind if you get hit at this point, as aiming for no hits can get quite frustrating here. I wanted to show it&possible, but it costed me a considerable amount of tries. There are more than enough extra lives in the game anyway... You may even notice I wasted many lives between secret stages 1 and 2, because the game doesn&give you further extra lives if you reach 99, and I wanted to show every available extra live in this walkthrough. About this walkthrough: I call it "perfect" because it shows you how to get the 4 possible perfect messages (all purple and red diamonds, no hits or retries) on every stage in the game.
