Test the Difficulty Curve Before You Add More Levels

More levels will not fix a prototype with a broken difficulty curve. Build one tuning lane, run three passes, and make the ramp readable before expanding.

Test Save Points Before You Expand the Map

A bigger map will not fix a prototype that forgets what the player earned. Test save points while the world is still small enough to break on purpose.

Test Enemy Telegraphs Before You Add Smarter AI

Before you ask AI for smarter enemies, test whether players can read one attack. A readable telegraph does more for early combat than another behavior tree.

Build a 30-Second Tutorial Room Before You Add More Mechanics

A tutorial room is not a lesson plan. It is a stress test for whether your first playable teaches one action, one risk, and one goal without extra explanation.

Set a Spawn Budget Before You Add Enemy Types

Before you ask AI for more enemy types, test how many threats the first one can support. A spawn budget tells you whether the loop has pressure or just clutter.

Test the Camera Before You Add More Rooms

A camera can make a small AI prototype feel readable or broken. Test framing, look-ahead, dead zones, and room bounds before you ask for more rooms.

Test Three Scoring Systems Before You Build More Levels

Test Three Scoring Systems Before You Build More Levels

Before you ask AI for more levels, test whether the scoring system changes how players behave. Three small variants can tell you more than another batch of generated rooms.

Test Input Forgiveness Before You Polish the AI Prototype

Before you polish an AI game prototype, test whether the controls forgive normal human timing mistakes. Coyote time and input buffering tell you more than another art pass.

Use AI to Generate Three Failure States Before More Features

Use AI to Generate Three Failure States Before More Features

A playable prototype needs a way to fail before it needs more features. Test three failure states, then keep the one that makes the second attempt better.

Write a Prototype Contract Before You Prompt the AI

Most bad AI prototypes start as vague requests. A prototype contract makes the prompt smaller, the test clearer, and the first playable easier to judge.

Your Weekend AI Game Tool Stack Should Stay Small

A weekend prototype does not need twelve tools. It needs one way to make the game playable, one way to make assets, and one way to judge the loop.

Move the AI Prototype Into an Engine Only After It Wins a Test

Do not move a prototype into a full engine because it exists. Move it because a specific playtest proved the loop deserves deeper control.

Test the Rule Change Before You Add Content

AI makes it easy to add more. Better builders use that speed to compare rule changes before the prototype turns into a content pile.

Build Games With AI Without Losing the Game Part

AI can make game creation faster, but speed only helps when the core loop is clear. Start with the playable part before expanding the world.
