A couple more games, this time in TI-Basic

We mainly produce news items about programs written in native code, but there is work and even some form of inventiveness in pure or extended TI-Basic programs.

The recent Descent Delivery, again by Josiah "JWinslow23" Winslow, is noteworthy in that the code of the single pure TI-Basic program is written to adapt to the whole family of (semi-)recent models, from the 83+ to the TI-eZ80 series (CE) through the 84+CSE, which is relatively infrequent: some programmers don't attempt to target both monochrome and color calculators, and others do it through multiple programs. Throughout 15 levels at present, the game's principle is to push a packaging box from its original location to the target delivery truck, through a series of segments delimited by walls, taking advantage of some items while avoiding others. There are blurbs of text at the beginning, and after solving every level... but let's not give away the story they tell ;)

In 2016, Kevin "xlibman" Ouéllet reimplemented another game from Josiah Winslow for the PC and Atari 2600 in extended TI-Basic for the TI-eZ80 series, yielding Wal-Rush! CE. As you can see in the screenshot, the game's goal is to guide the flying walrus on a fish-eating quest, while avoiding spikes and mines, and of course the clam and the cloud levels the bottom and top of screen. The older version of the game manages to use CE TextLib in creative ways to display a whole screen of non-text content - good job bending it to his will. The newer version, which uses the Sprites library by "grosged" (you need Sprites version 3.3, the latest one at the time of this writing) like the previously featured GalagACE, displays faster and more detailed graphics, shown in the screenshot below.
