I saw you post this game in the discord and jumped at playing it (no coding pun intended). I was waiting for a game that interpreted "loop" as it's coding meaning of i.e for/while loops etc. Solving these levels using your own implementation of a compiler/interpreter for basically assembly code was very fun :).
I loved how the different buttons and pressure pads added challenge to the levels. Furthering the loop theme by making the player end up with the correct program counter position and robot orientation for the next loop around the maze was a great idea.
One minor improvement, maybe make it easier to get back to the main menu without having to refresh the whole webpage (there may already be a way to do this but I couldn't find it).
Was an awesome game, congrats.
My game is below if you wouldn't mind checking it out that would be great. It hasn't seemed to have attracted too many ratings so a few more before the rating period deadline would be awesome, thanks.
