Not everything about Sunshine Alley is self explanatory for new players and can lead to confusion

There are event triggers that will present some of these hints when relevant.
For example leaving starting stones and not knowing why you cannot break bushes for resources.
The hints are displayed once then saved as seen, to not repeat itself for the same event. If you accidentally click it away, last hint returns easily by clicking F1\

Most hints are left to be discovered naturally or seen when teleporting to not present an unnecessary amount of hints / guides, trying to keep it at essential, most asked, potentially confusing features.
