There are times when you seem to have to pick one of the two possible options. One such issue is the controls of the game. You might wonder whether you should have mouse or keyboard controls in your game.
The answer I recommend: Have both. If possible, set the controls so that players can use mouse or keyboard. Let them choose. I found this way to sort out issues very useful. Sure, it’s extra work (at least some extra work), but that put player in the position to decide.
It’s not always useful, but think about it. Don’t automatically assume that you have only two options: A and B. Sometimes you can have A, B, and A+B or even new option C. Expand your thinking.
