This is really cool! So far I have a high score of 65612 :) Some feedback: - When opening the help menu, it wasn't obvious how to close it (I think the only way is by pressing '?') - I like the Goblin music! - It's a pretty nice interface to play with the instructions and I appreciate the color coding. It would be neat if there was a "sandbox mode" where you could preview the effects of running an instruction, and maybe modify your program once the game is over. I could see this being pretty useful for someone learning ARM assembly.
