Welcome to Calcuzap, a high performance shoot-em-up among the first non-BASIC games ever released for the TI-84 Plus C Silver Edition, TI-84 Plus CE, AND TI-83 Premium CE calculators.  This version of the game updates collision detection to check pixel-by-pixel instead of only checking if the bounding rectangles overlap.  It also includes performance optimizations speed up gameplay on higher speed settings on the TI-84 Plus C Silver Edition (the other calculators already ran at full speed).  Thanks to Kirk Meyer for Lite86 II which is used to compress the game to fit into a 16K (one page) flash application on the TI-84 Plus C Silver Edition, and keeps it under 11K on the TI-84 Plus CE/TI-83 Premium CE (where LITE86 runs in Z80 mode).  Can you win this game when set at both the maximum speed and hard difficulty?  Good luck -- you will need it!  If you do make it, be sure to watch out for the next release with even more levels, coming soon to a color calculator near you!
