In Good Cop Bad Cop, you have to choose where you will aim your gun from a list of players around the table. There is simply a button in the action bar for each player. 
This works perfectly on the web. However, on mobile, sometimes you will press one button and it will think you pressed a different one. This makes you aim at the wrong person, which is a pretty big deal.
Has anyone else had that kind of issue? Should I just make the action buttons bigger or add some left and right margin to them in CSS? Or do you think I have to do something more drastic like remove the buttons and ask them to click on the player in the player board or on their name next to their cards on the table?
