This is so wonderfully done. I've been looking for something like this for a while.
Just one suggestion/request... It might be better if some of the other levels were unlocked at the start rather than the angry birds unlock method considering the target audience. Some kids might want to jump straight in to the tougher problems.
This is well put together and pretty fun. Obviously aimed at kids in a particular age group specifically, but adults who would competely turn their noses up at this probably deserve a lengthy time-out. You could do a lot worse with your dollar (a lot worse) than to support a game like this on the app store.
Thanks for the feedback!!! wasn't expecting a conversation here!
You hit one of our doubts TheloniousMac, we probably are forcing some users to practice things they don't want / need. The update will definitely open the first level for each world / opeartion from the start.
We really tried to polish a game that was basically a mashup of basic gameplay and basic arithmetic, with good graphics and feel, but with only math as the mechanic.
