Steam App ID: 749880

This is a very simple game,you can play it just with the SPACE button\.But we should pay attention to that players must have enough endurance to finish the game in one time\.If the players give up halfway, they will start again\.  ====About The Game==== The game character Jhon J \(JJ\) is a crazy collector of diamonds\. In the game JJ will not stop walking forward,players just press SPACE bottun to control him jump \(different jump position will have different effect\)\. And then JJ will get the diamonds, of course, if JJ touch the dog, he will be sent to the hospital\.  Items of the game\. 1\.Fireworks        2\.Ice Ground        3\.Chairs        4\.Tyre         In fact, there are some hidden secrets in the game, which is also our tribute to the classic games\.  ====About Us==== We are a new team, and we have only two months to make the game from zero\. We also studied the music,and made severial BGM for the game in a short time, hoping to give you a refreshing feeling\. The game itself is not very difficult,we hope that this simple game will also bring a little joy to everyone\. But there are also a lot of shortcomings and BUGs, we hope to get more help and support\. As our technology progresses, the game will be more better\. ：）
