Hello.
I am understanding I am not to write a program that allows you to import/export PNG files to and from P8 cartridges, so I wrote this in an attempt to assist other Pico-8 users of the educational edition since they cannot import or export graphics or music.
It uses a variance of the graphics for the little library I wrote, the first Picotron program written found HERE:

I exchanged the spider and bomb for Forest (tree) and rubble which can double as mountains. There are some miscellaneous sound effects and I also added a musical note player that overlaps the notes as they play so they sound better.

Users of the educational edition of Pico-8, you can copy this code by clipboard and paste directly in your source-code. It not only has 128-characters and game sprites but a fairly robust library of sound effects and the ability to play notes overlapping each other.
If you found this helpful or have further questions, please let me know.
Thanks !
