A simple game for iphone

Say "I understand" to prove you have read and understood. Users have to answer a question(level 1 = question 1). Each question will have a different time limit. As they complete each level(100 levels in total) the levels get harder - harder questions and shorter time limits. When they reach certain levels, like level 10 they receive a badge(achievement) saying they have completed that level. If they fail they start from level one again. In app purchases - can buy time extensions and hints.
