Jeremy Rand	88ea840e23	Update the flea sprite as it drops. Add random routines. Thanks to John Brooks for those. Use the random routines to pick a column for the flea to drop from. Also, randomly leave behind a mushroom as it falls.	2020-07-19 15:15:45 -04:00

Jeremy Rand	a718c8caef	Lots of general sprite cleanup. Add sprites for the ship and the shots and include collision detection in those routines. I think all of the drawing code is done now, maybe?	2020-07-09 22:55:08 -04:00

Jeremy Rand	598934446b	Finish the spider sprites and the explosion sprites. Remove "and" masking from the spider and scorpion sprites because they will be drawn first and will not overlap with anything on the foreground. Split the sprite.s file into a series of smaller files for each type of sprite. Add a file to describe the overall plan for the design of the sprites.	2020-07-02 22:57:52 -04:00

Jeremy Rand	a9810ecb75	Well, it launches, clears the screen, waits for a key and then quits. But it is a start.	2020-06-10 23:51:53 -04:00
