Wow, I don't even know how to answer. Thank you so much for such a high praise! I'm stunned you liked it so much, but I'm gladthe "aha" moments worked so well then. They were the main goal of the puzzles : I didn't want to make them too hard, I wanted people to think out of the box about the trajectories the bumblebees needed to take.
Again, thank you for such a kind review!
