Nice to see it also exists for other stuff. IMHO since TI calcuklators are in constant battle against mobile devices to keep a decent audience number, it's good if when ports of mobile device games to calcs are done that exclusive features are added or if other stuff get changed so that the new version stand out and attract more people. Otherwise if there is the same game on both Android and TI-Nspire CX devices, people will be more willing to go toward the mobile phone than the bulky calc that lacks sound/phone features since there will be no point in playing the calculator version of the game instead.
