I really wanted to be able to actually use IGT but it's not possible for this game.

If you complete a level and then click "Retry" on the results screen, it doesn't restart the level, but instead puts you back into the level with all the objects you had just moved to complete the level the first time still in their places.

The fast-forward option speeds up the IGT. Unless you did levels first try (as tapping the "Retry" button makes the IGT inaccurate as the part about it moving objects for you applies here) then that would be the only way to have any legit IGT. So RTA is standard.

Any collected Hints are not allowed.

You must play on a completed save file. That prevents the slow few seconds of unlock cutscenes for new areas and also the nearly 2 minute unskippable intro cutscene when using a new save file.

Main Zones is basically New Game. I call it main because it's the main sets of levels you have to complete to finish the game normally.

There's 100 main levels. 150 if you play all of the Zone 3 levels.
