A free planning tool
Playtest brief.
Start with a test from a guide or write your own. Record the build, the steps and what happened, then save, download or print your next change. Your notes stay in this browser; downloading gives you a separate copy.
From the guide to your game
Start with a useful test.
Choose a guide to see its starter. Using it replaces the open form; saved notes stay unchanged until you save.
Check a finish, a failure, interrupted loading and the next run.
