You know this game did a good job when it took me a while to check all the luggage perfectly. Would be much better if there was replayability of some sort, maybe randomly generate the contents of the luggage or something similar. Though in place of that was the clever design of each luggage, I really liked that you (as the player) actually need to put some effort on looking into the luggage.
Overall a really good game, very polished and had lots of fun with it!
