I always wanted to make a gallery shooter with invaders possibly from space. I would've drawn these on graph paper, and then entered in the LOGO-style DRAW commands to draw them in color on the Tandy, using 320x200 16-color mode. Once the sprites are captured by the GET command, you can PUT them to the screen more quickly.

The design of the invaders was inspired by TI Invaders for the TI-99/4A, where many of the designs would have elements that did not move relative to the viewer as the invader moved across the screen; legs, windows, eyes, etc. This is much like a running animation where the foot is planted and does not move as the character moves. I remember wanting to capture this design element in my graphics.

GW-BASIC was not nearly fast enough to make even a 10 frames per second game, except maybe a few objects in motion.
