Start with the game loop
Write the core action first: dodge, race, match, build, shoot, cook, survive, or solve. Then add the theme, scoring, difficulty, controls, player count, and whether the game should be competitive, cooperative, party-style, local, or online.
Play and iterate immediately
Instaplay generates the game, assets, and controls together. Play the result, adjust parameters, and ask for changes until it feels right.
Good prompt formula
Use this pattern: game type + core mechanic + theme + scoring + controls + social twist.
Example: a two-player online cooking battle where players throw ingredients into moving pans, score combos, and sabotage each other with freezer powerups.
