I didn't even know you could make games in React, so that's really neat. If you want to use JavaScript for your game development, you might want to look into using another library though - I don't know too much about React specifically, but I'm pretty sure it's more geared towards web apps. A proper engine might give you a leg up in terms of things like input handling, animations, and the like. Regardless, it's always cool to see out-of-the-box creations like this. Good job!
