The reason why I chose the story to have the bad guy win is because of the antibiotic-resistant bacteria - super bugs.
The game will be for mobile device and I think that it will be good for little children in junior schools.
Here are my other two ideas.
Here I though of making a story of conquest, something about knights and warriors.
I'm not sure if this is suitable for little children and it may give wrong message so I think this is not going to work, but I just wanted to share it anyway.
In terms of design I'm definitely thinking of something simple. I was looking into some indie games and I think I found the look I'm aiming for.
