It´s such a shame that this game is unplayable :( The concept is great, but it becomes unbearable when you have to replay every third day or so because 1. the day won't start, 2. the day won't end , 3. the day won't end because a customer gets stuck in front of your soda machine /sample machine (actually, this glitch won't let me move forward at all unless I delete those items, thus making no room for shop improvement). :(
I think that's due to the fact that I updated the game. I'm very sorry for that!
