Using it
From a rolled idea to a playable game
An idea is worth what you build from it in the first week. These three steps are the difference between a place file you finish and one you abandon.
Build only the first playable
The first-playable line is scoped on purpose. Grey parts, no shop, no saving. If the loop is not fun with placeholder art, art will not save it.
Play it with two people
Watch where they get bored and where they laugh. Keep the twist only if it changes what players do, not just what they read.
Make the world move
Idle NPCs, a shopkeeper, a monster that stalks rather than slides. Generate each one from the prompts on the idea card and drop them into Studio.
Why animation
The fastest way to make a new game feel finished
Players forgive grey parts in a prototype. They do not forgive an NPC frozen in a T-pose. NPCMotion turns a sentence or a phone video into an R15 animation you can use straight away.
Type the move
“Shopkeeper wiping the counter, glancing up.” Describe it the way you would brief an animator and get it back on R15.
No skating feet
Foot contacts are locked and limb proportions re-solved for R15, so a walk lands like a walk instead of moonwalking across your lobby.
Ready for Studio
Download it for Studio or copy it as a script, then load it in the Animation Editor like anything you keyed by hand.
