I got fired D:
Nice game! Bob really sounds like me when someone wakes me up in the middle of the night haha
Turning around/driving backwards out of the deadends was a little annoying, maybe you could add a more "realistic" city structure where there are blocks cou can drive around (of course some deadends will still be nice, just not all of them). The guessing the code at first looked like sth I need to search for in the environment but the fact that I couldn't leave the screen drew m eye to the worn out buttons so that got easier :D
Its a little sad that I got the same code twice and the task is so repeating but with some more work this could be really fun ^^
