Good idea. How about a touch-screen version?
Game: Heart Hero
Heart Hero - Drum your heart.
Stay Inside The Box: The whole game takes place in just one screen, no scrolling or changing screens in any way is allowed.
10 little pigs: The game uses 10 or more buttons or keys for gameplay-related actions (no pause or anything else).
Approved for All Audiences: The game must not show any violence, not even cartoonish. Stepping on living mushrooms is off the list, as is killing any type of enemies, not even undead, though we know they’re already dead…
May the (Web) Force Be with You: The game runs in a browser with no plugin.
