ZX81 Pirate Invaders v0.2

Continuing this game development for the Sinclair ZX81 in assembly code, and this is what I have so far. The game is based on the classic arcade shooter but with a maritime twist! Instead of aliens to shoot at it will be the pirates, symbolized now by "peg leg" pirates with their swords waving. The previous "Skull and cross bones" sprite will come into play as the end of "wave" boss to kill - not yet coded that though. I've also made the player's ship half the hiehgt to give more room for the pirates coming down.
So far the player's ship can move left right and fire it's "cannon", the pirates move left and right and down one row at each end stop. There's no scoring yet or even any hitting the enemy. There is logic in to draw the pirate only if not yet dead, but I've not coded up the cannon ball and pirate hit logic.
