Thanks for playing the game! Do you mean the circle wouldn't appear when clicking on the coffee mug? It's good to know that we calculate the rotation circle even before the mouse enter the coffee mug's "rotation zone". This does not change when clicking and holding, so the following scenario is possible:
- A mouse is moving in the direction of a coffee mug
- You click and hold that coffee mug
- A rotation circle is calculated
- The mouse hits an object (like the little colored candies) while you're still holding the coffee mug
- The mouse gets close to the coffee mug, but will never hit your rotation circle since that circle is only calculated once
Could that be the scenario that you ended up in? As a player you can release the coffee mug and click & hold it again to fix that issue. Although, it would be a nice improvement for the game as well to recalculate the potential rotation circle (i.e. that calculated rotation circle before the mouse hits it) frequently.
