Easy, medium and hard level selections for players at each level.
Animation in game hint display.
Removed confusing operations like camelize and underscored.
Tutorial is easier to follow.
Quirky but can be mastered at least with the Easy challenges.
Not a lot of storage on the device and fun to while away some free time. One question though, how come all options are not available with each challenge ? Kudos to Qingfeng Yang for the free version of this app ...
