The atari 2600 even after all these years continues to get releases, heres another:

Alien Attack is a homebrew Atari VCS game by easmith. It’s a 4k tiny shooter game, fully written in Assembler.
Release notes:
Added a shield feature, activated by pulling down. Lasts one second, then you must wait 4 seconds. to use it again. Since I am waiting to have carts made while folks help me test it on real hardware , I might as well add more stuff….. Maybe difficulty options…
