Spark

You can try spamming your way to victory, or attempt to use skill... either way, you're going to need some luck.
In Spark, you are the bearer of a unique arsenal of four different bullets (yeah, we also call them sparks), each one varying in speed, color, and power. Each Spark interacts different with the next, allowing for dozens of potential combos to crush your enemies. You will have to use your knowledge of the Spark to push your way through the daunting first chapter of the Spark campaign, featuring epic music, lots of enemies, and three Bosses that are sure to test your skill.
If that proves to be too easy for you, then you can head over to puzzles where you can refine your skills with the Spark combos to complete 20 different challenges, each getting progressively more difficult with new obstacles standing in your way.
Is that still not enough for you? Well, then you will have to truly test your endurance in the Spark survival mode, featuring Powerups, endless waves of enemies, and a Steam integrated leaderboard to prove that you are the one true master master of the Spark.
