BooMfire (ZX Spectrum)

BooMfire is an implementation in ugBASIC for the Sinclair ZX Spectrum of the well-known DOOM Fire effect. It is my entry to the 2024 edition of the BASIC 10 Liner contest, SCHAU category. The downloadable version includes the source code and documentation.

You can change the fire effect by pressing one of the following keys:
1: fire above the BooM logo,
2: fire across the BooM logo,
3: fire behind the BooM logo,
0: extinguish the fire.
