Lots of fun and LOVED the ending.
Many puzzles, most were fun, a few didnt make a lot of sense (the pipe puzzle) and a few I had to go to appunwrapper to verify I was doing the right thing.
Best thing I did -- make a detailed map as I went, naming the puzzles and crossing off puzzles as I completed them. That way, when I found a new object or clue, I could check my map for where it could be used. Otherwise, I would never have remembered all the puzzles that were pending. There is no teleport so my map saved me a lot of trudging around too.
Annoyingly, the notebook holding hints was difficult to bring up and didnt stay up during puzzles. For lengthy codes (moon phase), I transcribed to paper so I could consult the note while the puzzle was up.
I would give another star if I didnt have to take my own notes and there was a teleport feature. Better help system would be nice too.
