A built game is not final. You change it by describing what you want in a chat panel beside the game, and every version is kept so nothing you liked is ever lost.
Revise by describing the change
The chat panel sits next to the running game. Write the change the way you would say it out loud:
Slow the enemies down.
Add a fractions question to level 2.
The timer is too tight for a five-minute round.
TutorFlow rebuilds the game with that change applied, and the new version goes through the same two checks as the original: the automated validation, then a real playthrough. A revision costs 10 credits, slightly below a fresh build.
You never edit code. If a change is easier to show than to say, say what is wrong rather than how to fix it, and let the rebuild work out the how.
Version history
Every build, revision, and restore is recorded. The version dropdown in the editor lists them, and each entry says what changed rather than only a number, because a bare version number tells you nothing a week later.
Any earlier version can be restored, which makes it the newest version rather than overwriting history. A restore is recorded too, so restoring is itself reversible.
This is what makes revision safe. A change that made the game worse costs you one restore, not a rebuild from scratch.
Settings you can change later
Title, description, and audience can be edited at any time from the game's settings. Changing them does not rebuild the game.
Dimension, play length, visual style, and persistence describe how the game was built. Changing your mind about those means a revision, since the game has to be rebuilt to honour them.
Share it with your class
A game is private by default. Nobody outside your classroom can open it, even with the link.
Switching it to public produces a URL you can hand to learners. They open it in a browser and play. There is no account to create, no plug-in to enable, and nothing to install. Keyboard and touch both work, so a shared classroom tablet is enough.
Switching a game back to private takes the link out of service immediately.
Before you share
Two things are worth doing once:
- Play a full round yourself. TutorFlow has confirmed the game runs and responds to its controls, but not that the difficulty or the questions suit your class.
- Open it on the device your learners will use. A game that reads well on a laptop is worth a look on a classroom tablet before the lesson rather than during it.
