What is the difference between the paid version of the game and the free one?

hey i was playing super market simulator prolouge for 2 to 3 days but now some happened that when i opened the game the continue button as well as the new game button was not working pls try to help me. pls reply

im clicking on new game and contine and neither will load not sure what to do any help?

The game has been constantly crashing, making it necessary to restart it. I haven't been able to play for more than 30 minutes at a time without this happening, so I have to save my progress every 2 minutes so I don't lose anything... This same problem has happened on two different machines. Does this situation also happen to anyone?...

The only complaint i have with this game so far is the fact that customers buy multiples of single items. Does someone really need 6 packages of toilet paper. Limit the amount any single customer can buy of any single item, like only 1 with a low chance of buying 2. Nothing worse then stocking a shelf then a single customer buys it all, then the next customer says they cant find this product, because you haven't restocked it yet. Great game though....
