The Swapper

This is a wonderful game that requires reasoning to make progress. An excellent intro and simple controls help with the slightly complex gameplay. It feels like a blend of sudoku with hard sci-fi. The age rating is going to depend a ton on your kid's personality. If they like mysterious things it seems like a great redirect from other games or stories that may also have undesirable traits. I haven't finished this fairly long game yet, but I think I'm far enough in to have a sense of it's character. It also asks some serious questions about what makes us human and what alien life could be like. Overall, this games makes you think.
