I liked this game. It was fun to play, the idea is good. Only, as others mentioned too, the controls were a little bit confusing at the beginning. I wish they were more intuitive . I would love to see a little bit more variationss between customers, because you went for a comedic style, they should talk more and maybe throw a joke here and there for the fun sake.
Overall i like the idea itself, the stick man style and the usage of audio.
