Jet Propulsion (Free early access)

This is a port of the classic ZX Spectrum game Jetpack (https://en.wikipedia.org/wiki/Jetpac) for the Atari 2600.
It features wave one, two and three. No score in this early version.

It may have some bugs here and there.

You need an emulator (like stella) or the real hardware. I use the Harmony cartridge.

Please, tell me what do you think about this game.
