Hi! Thanks for your kind words.
Hive Time is intended to mostly be a relaxed experience, but setting your own constraints, such as trying to build building the smallest possible sustainable hive, or avoiding research/cell upgrades. For players who aren't good at finding The negative effects of the Royal Decrees upgrade can provide some further challenges and variations (for example, halved Beesitter efficiency can have a big impact on a growing hive).
If you're interested in future changes, you can read about currently planned additions over here.
Hope that helps!
