I've made some adjustment to the game. Currently there is one issue. I made a forum thread for it: Issue
Font color of the numbers changed to black;
Font of the numbers changed;
The last number block is always yellow;
Made some adjustement to making of the grid and placing of the blocks to make them more centered;
Fixed the bug when the give up screen and how to screen are open at the same time;
As soon as the issue is solved i'll upload the updated game!
