Kirby's Infection Crisis

User prompt

Kirby infection au game, control kirby. If you get infected, you don't lose control (but will die in 1 min if not going in water once in that min then after water bath timer goes away and kirby is cleansed), you lose control for 20 seconds (then see dont lose control for happen next), or you die immediately, chosen randomly. Avoid infected Waddle dees, avoid normal and infected Waddle doos, and try not to get infected! Defeat Dark Matter to save Dream Land!
