ZX81 Fly Low Hit Hard
A downloadable game
download the fly.p
(or fly.wav see below**)
Install a zx81 emulator such as EightyOne https://sourceforge.net/projects/eightyone-sinclair-emulator/
Set the memory size to 16k
Open the .p file in the emulator and play
The keys are x up, n down. space bar or key to fire (also Cheetah joystick enabled if you play on real zx81).
**To play on real zx81 you'll need to download the fly.wav then play the audio wave file over into the zx81 using a standard mono headphone lead from your audio (eg smartphone phone or laptop) into the zx81 EAR connector. You'll also need a 16K ram pack for that. I'm assuming if you are attempting this then you know what todo!

realised my emulator was running slightly faster than realtime !! so that's why it ran slightly slower on real ZX81, anyway I just rebuilt with reduced delay loop so runs faster, whilest hopefully still being playable
I need to revisit this and add things like extra levels with different landscape,. possibly into a cave as well. More different enemies, different score for different enemies - multi rate enemies would be better, and one that track
updated with extra features:
1) you now get a new life at every 100 scored
2) text is printed when SAM launch warning at bottom
3) the missile smoke only extends 3 blocks below the missile so is (remotely) possible to dodge it from below. You can still shoot the missile if you're skillful enough :)
4) ground is no longer "shootable"
5) enemys now bigger but less of them (mercy!)
Stay posted for future updates
