Devious, pretty, cleverly done, and after a few stumpers, overall very solvable (in 2200 clicks!) For a few, I just didn't realize I had access when I did, or how to access.
I liked the puzzles that trained up (like the stars). But oh, that screwdriver!
Found out what I needed to do....and it didn't work. No interaction. So I tried reloading.... and no saved game. Oh, wait, it may be I misremembered how to apply it.
