Here's what I did with Cosmocrash in the last 21 hours.

• added in the spinners. As promised they're white characters, but if I have room left at the end, I may change them to sprites.
• made it so the score decreases by one if a meteor hits, and made the lives decrease by one if a spinner hits.
• made a game over situation, so the player can press either fire button to start a new game.
• in order to get plus graphics in here, I apparently can't have black characters, so I changed them to yellow.

I have a lot more things to do though:

• hook up Intellivision and play Astrosmash
• add in color changing grid
• add in other stuff I see fit.

So now, after four days, it's in a "technically a game" status. But I have more stuff to do, and around 1k to do it in.
