Wow, I love this. I'm not sure if its just me, but I cant escape the options menu in the browser. Maybe I misread or didn't notice a button.
Reloading the level doesn't let me enter the commands again so I have to reload the page to try a different combination.
Other than that, the animations, the sound, the entire premise of the game is fantastic. Its well polished and it shows.
If I had to recommend one thing, I'd make the UI scalable. I know its a bit pointless for game jams, but It would help to clearly see the whole level when planning which instructions to use. You did great well done!
