Now the game looks like a normal runner, but you can still add other game design elements to make the game more fun and give it more user interaction. For example, you can add sound effects or particles as we explained in the previous chapters, or add some more obstacle types, animated ones or animated laser beams. Alternatively, you can add more collectable types and power ups. Or maybe you can force the level to shuffle between the blocks and never show them in the same order. Maybe you can add a small missions system to force the player to achieve some missions and tasks from his gameplay. There are so many game design ideas you can use, but game design is a different topic than the target of this book.
