Oh! Sorry about that, actually both, unusual way and glitch! I think I have solved both of them (at least the cork issue is sure solved). Sorry for the inconveniences and thank you for the report!
Okay . . . but 16 is now a different puzzle. Though I see now why you're so partial to that solution (and why it took me another couple of days). I guess I'm just surprised that covering all the targets isn't what's required, as in Sokoban. If a player has to find "the" solution as opposed to "a" solution, matters get even dicier, and hazier. This is commentary, not criticism. Greatly enjoying your game, as usual.
Oh, sorry, maybe I wasn't clear, that level in particular had a glitch where it was impossible to win, it didn't depend on the solution. On top of that, you found an unintended solution that I had to fix to ensure that players learn what they're supposed to in that level. But currently if you find another solution that's not the designed one, the level will be solved. Thank you very much for playing and leaving your thoughs!
