Best Score NaN after multiple UNDOs. Save previous game

Hi

When I click multiple times Undo sprite and curStep becomes 1 after next click on it BestScore becomes NaN. How to fix that?

Additionally: How to save to local storage previous game? So a user could continue to play it later.

Thanks.

Use 'On item get' then set corresponding variable or array from the value.

I tried like on the screen. Did not help

Local Storage stored as string so convert back the value first to number with 'int'.

Tried (in both places):

System Set BestScore to int(LocalStorage.ItemValue)

But it did not help.

Added Get item "Best" for both events. And it works even without int(). It it a good solution?

If that way it works then proceed. Sure you can get away with 'Get item' when an item is exist yet incorporating 'On item get' just to make sure retrieving process checked in procedural way.
