In 1996, a PC game called SQRXZ came out. Released by Maze and Hojo, it was later ported to the TI-85, TI-86 and TI-92 by Jimmy MÃ¥rdell and later to the TI-83 and TI-83+/84+ series by Solignac Julien and became a classic on ticalc.org. In 2015, it was ported to the TI-Nspire CX by gameblabla, along with SQRXZ 3 and 4.
But now, the TI-Z80 ASM version has finally made its way to the TI-83 Premium CE and TI-84 Plus CE!

This game is inspired from Mario series, but with generally much more challenging levels, although custom levels from the TI-83+/84+ version are supported and a CE level editor is supposed to be released in the near future. The gameplay is very smooth, with a frame rate approaching 60 FPS.
