Thanks to Bruno Marie (Gameblabla), Sqrxz is heading back the way it came from, to an calculator! Sqrxz 4 has been ported and is now ready for your TI Nspire CX! Backports of the first three parts are very possible and might happen over the next few weeks.
A ridiculous amount of coffee was consumed in the process of building the Sqrxz games. Add some fuel if you'd like to keep us going!
