CoCoSmash

CoCoSmash is a space rock shooting video game for the Tandy Color Computer. It is a (simplified) clone of the 1981 Astrosmash game for the Intellivision by Mattel Electronics.

The program requires a CoCo (real or emulated) with at least 64 kB of RAM. The game runs in the PMODE 4 (256x192) graphics mode. On a CoCo 3, an RGB monitor is recommended.

The current version is 0.1.0 (2026-03-05).

I can be contacted (in French or English) at sarrazip at sarrazip dot com.

As of Winter 2026, the game may need adjustments to become difficult enough but not too much. The game could also stand to have better sound effects. Comments are welcome. There may be updates to this game in the future.
