Collect hearts, avoid dragons (or zap them with a laser beam - space bar, or shock them with a meow - "s" key). The laser beam and the shockwave have different cooldowns, displayed by the 2 bars at the top. The more you collect hearts, the faster the game scrolls. If you get hit by a dragon, you lose one life.
Project for Exning Primary School, will add more features as the club progresses
