Excellent game, possible bug
So many games are lame immitations of existing games, but this has unique puzzles I've never seen anywhere else.
I wonder if there may be a bug in the log one (#8?) all logs are down and highlighted in green except the shortest one, but the system doesn't seem to want to accept it. I've thought other things were bugs, only to realize I just didn't get it - but in this case it does look like one.
But excellent work either way
