Looked tricky, but was actually quite simple. Very well made!

nice game

Thank you! :-)

No, sadly it did not. I guess every Tim has to get into one specific buiding. That's not what I read when I read your description. That's why I still commited the solution, since I think it is kind of unfair to leave it to the player to try the whole permutation of possible assignments. That would be 27 possibilities (3^3). If you do a puzzle like that, you need to describe which Tim has to get into which house. I admit that you can get the idea that every Tim has to get to the house the closest to him on the x axis. Still I think you should definitely make that clear.

Apart from that I enjoyed the puzzle.

@Soylent Clever! Did that actually trigger the "puzzle completed" dialog? You should have to get one Tim into each house to actually complete it...

Done with 3 spare parts. Can it be your description is wrong?
