Thank you very much for playing and the detailed feed back. It will help immensely to improve the game. The sizing of the customers was indeed intentional :) Glad that it shows. Additionally It was suppose to show in the top left corner what size the player holding, but it got broken in the final build, I'm already on fixing it.
I'm really glad to hear that in the end it was so good that you didn't want to go on vacation :) I intend to continue development so please consider following and stay tuned for an update with fixed and new features in the future.
