Thanks for playing and giving feedback! I have already started making updates for the game. I removed customers and added random order what you have to memorize for couple of seconds. I also removed the timer. 

Wow! That's a good score! I am currently working Android version. It's going to be lot easier and there is random order every time. 

Thanks for playing! 

Thanks! I will make the game easier when I am going to publish it on android. Now it is like a memory game
