Additionally, it features an intelligent hint system to avoid getting stuck at a certain level, and an automatic error highlight to help you identify your mistakes.  Most importantly, it supports offline gaming and even has an auto-save progress feature. However, the ultimate drawback is its shallow learning curve for some of its modes.
