Wow...
I love this series, but this one was harder than the others by far. Not so much because the puzzles were tougher, but because they were IMPOSIBLE. Using the coin to unscrew the toilet seat and the other to clog the drain? I don't think any1 could have figured that out without the guide. I think you could have thought out the puzzels out a little better. Overal really fun, just confusing...
