Stage 17... Not that hard, and it can be completed using only your two scrolls without knocking over the stone blocks. Just try it and see if you can do it... It takes some skill and timing, but it can be done. Not too hard if you ask me, though it did still take 5 minutes.
...Is it strange that, before I started playing this, I though the picture for the game was a picture of a walking piece of toast with arms and a face? In fact, that's the reason I didn't play it sooner... But it's a good game, even if the picture for it is of a living piece of toast.
