ZX81 Jump
A downloadable game
This is a fast paced platformer. The enemy robots lie in wait and will kill instantly. You start with 6 lives and a "plentiful" amount of time to reach the last room.
Partly a nod to the famous ZX spectrum game Manic Miner, but is very different (not least because it's written for the zx81!!! It has quite big "sprites" for the enemies and the player. Expect future updates where I may improve the functionality in the game like improvements to or new rooms. TBH it's more stable now after version 1.5.1
If the time reaches 10 minutes you lose all but one life
If you hit enemies you lose a life
Download

If you want it possible to convert the jump.p file to an audio file(google it) so you can load into a real zx81, or if you have a ZXpand you can just drop it on the sd card.

Version 1.5 has improved collision detection, it's tougher to play, as even the slightest touch of the enemies can kill instantly.
new version fixed the gold collect bug, and improved the collision a bit, I don't normally like to use the phrase but maybe it's "fundamentally flawed!"
added a poisoned arrow flying across in two rooms
added another room and doors can now be on the left side of the room - but you still go forward, rather than previous room. It's on version 1.3 now, definitely worth re-downloading
V1.2 has vertical moving enemies as well as the old horizontal ones. The next update will be to add more rooms and possibly a code for a poisoned arrow flying accross
Now in V1.1 - 10 rooms total, and the players starting position can potentially be anywhere on the screen, only 2 rooms currently use this though.
now added flashing gold (dollars)
added a better ending and the "leave your shoes behind" bug has been lessened
