This could be a cool puzzle game for students to familiarize with assembly for sure, but definitely needs more polishing! Of course it could benefit for some visual and audio upgrades, but most of all, it needs a slower introduction of the mechanics and different instructions. It was a bit confusing, and that considering I studied assembly some years ago, imagine for someone new!
If you tweak the levels (making the first levels super easy and introducing new instructions one at a time) you could end up with an interesting game - then even expand adding for example corrupted registers to have more winning conditions. Definitely check Pony Island if you plan to contiune this project, it does a great job by making "programming" easy, and you could apply some ideas to this game
