Hopefully this will inspire someone to take on this challenge: Each line fits on the screen and there are no more then 10 lines.
It's like poetry but in programming :D
Use the smiletool (green button on keyboard) then click "paint" and go to "SP". Draw your sprites, then click save to save them under a file name in the project folder. Then just use a load command in your game.
(LOAD "GRP4:FILENAME",0). From there, you can define and use your sprites as normal (using SPSET, etc)
