I'm releasing Math Battle this Monday. It is a unique blend of very configurable math drills and a 3D space shooter. Here's the App Store link for when it is live. It will be free. If you're fast and can't wait till Monday here are some promo codes: T94TFAY43Y49 7MRAYAF3RWK9 463NTX6X7RAK TJPM73EKHNLL TA3TNME99NT4 If you miss out on the codes come back Monday and follow the link to get it for free. I've made a video tutorial for the game as well. I'd love feedback. This is a one man operation, so suggestions and ideas are welcome.
