Earlier today testing on Maths Rush completed and I submitted it to the Windows Phone marketplace review.
Maths Rush is an addictive little game that challenges you to answer 50 or 100 basic maths questions before the time run outs. The game starts out with 15 seconds on the clock. For each question correct you get an additional 3 seconds. Incorrect answers result in 10 seconds being deducted. Game over when you run out of time.
So far everybody I tested the game on always asked for one more go, so hopefully it has some lasting play value.
Whilst the first version is in review development of the next release is already started. This will include Global High Score and hopefully live tiles giving feedback on how your rank has changed. Couple other ideas but will keep those under wraps to see how they work after a quick prototype.
