I do not have enough gems

When something costs more gems than you have, Kovo tells you how many more you need. It then offers to take you to the gems.

That message opens over whatever you were doing. Closing it puts you back where you were, with the same screen still open.

Nothing is spent. The gems you have stay yours, and the thing you were buying is not bought. You can earn or buy more and come back to it.

This works the same wherever gems are spent, in the shop or on a muscle Level.
