Thanks a bunch.. c: . Yeah, i'm planning to add a tutorial as most people all most all don't know what to do. You can collect any colors.
Here how it works:
You collect 1 blue coin, +1 is added to the score.
You collect another blue coin, +2 is added to the score.
You collect another blue coin, +3 is added to the score.
You build the chain to get higher score but you only get 100 moves so you have to make them count. This can be done with any colored blocks. The golden block adds +20 to your score.
Once again thanks a bunch..

Edit: I've added a main menu image. Please let me know what you think of it.
