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. Updates: . Changed to space theme .Cloud Variable! Idk how to use it xd
Thanks to @YannLouchart for the code, and most of the sprites.
