Use of audience suited language

Going back through my work shed light on a few grammatical errors and misuse of syntax that I had not noticed when doing brief checks of ensuring the project ran smoothly. This included spelling mistakes and minor misuse of apostrophes- I am not going to go back and change these until they are grammatically sound. My test buddy Susie joined me in testing out my game and suggested that the use of 'you are wrong' in my incorrect answer scenes was perhaps a little too harsh for the audience of young children that my game is aimed at and perhaps I should alter my language to make it seem less intense than before. I have decided to use my remaining time today to go back over my work and change all of the 'You Are Wrong' to 'That's not right' which, in hindsight, feels a more suitable way of addressing the audience to which I am catering for.
