This isn't really focused on the gameplay itself but the lobby shop. I am going to take tower defence for example. LEt's say you are in the lobby and you wish to purchase a tower. You are looking around and you accidentally click one. It immediately says "Purchased tower". Mu idea is to add a screen where it says something like "Do you wish to continue with your purchase?" And it has green and red wool renamed YES and NO. This would be very helpful. Thank You!
