Clockwork Knight is a game about toys coming to life when humans are not around. Betsy's toys live in harmony with each other, but things take a turn when a rogue toy kidnaps the princess and causes trouble for Pepperouchau, a clumsy clockwork knight.
The gameplay involves side-scrolling action through various stages made of toys, traps, and household items. You control Pepperouchau as he navigates Betsy's room, then her brother Kevin's room with its complex engineering contraptions. Watch out for the jet transformer boss in the end of Kevin's stage.
Other stages include missions through the kitchen and attic. As you progress, you'll collect coins that can be used to continue playing when you run out of lives. You'll also meet other friendly toys who let you gamble with your earnings.
