Language
Vertigo is a TI calculator port of the NES game Marble Madness. The game was programmed in assembly by Matthew Shepcar, and released for the TI-82, TI-83, TI-85, and TI-86 calculators. The game is quite challenging, although the goal is simple: to guide your ball to the gem stone on each of the fifty levels. The levels are split into five worlds, and to complete the game you must win a challenge mode game on each.
The levels are displayed from an isometric 3D view, and on the TI-85 and 86 they are shown in greyscale. Unfortunately, the screen on TI-82 and 83 calculators is quite small and is too slow for greyscale to be effective, so the game may be harder simply because the display isn't as clear.
