Made it through the first 9 levels with only a little stumbling (as the author has indicated, there are plenty of little hints).

Level 10 has got me quite stuck though! I think I have an idea what needs to be done, but I'm stuck on trial and error with the exact details.

That said, there's something deliberate that I know is a hint and doesn't figure into my thinking... I don't yet know what it means.

Frustrating, but fun :).
