Just for start and add some motivation for this project :), need a lot of work.

next version will have:

• move restrictions (swap blocks if there will be match)
• special blocks (horizontal / vertical for collecting 4 gems in row)
• some animations
• music + sound effects
• main menu + options + fill screen + game modes
• infinity game mode
• level game mode
• better graphics (moving background elements, different backgrounds, better UI)
