sure!
spinning coins when you’ve got a lot of them and don’t have the upgrade that let’s them spin automatically. it requires repeatedly moving the cursor and then clicking; would probably be easier on the hands and wrists if it just required moving, or even just clicking (although just moving would be better).
selling coins used to be similarly uncomfortable. it’s now a non-issue due to the new feature where you can immediately buy the next upgrade as long as you have enough coins; i suggest mentioning this feature in the game description (i only learned it after playing a few games and getting told about it in a game over or win screen).
