Hi, you have to go close enough to the coffee machine to enter text.

There's some hints saying: "To answer the question, you must enter the adjacent tile."

ahhh i see, the problem was that i just clicked the "Foo Bar" sign... which let me in but didn't bring my little avatar dude alone with me.

Yeah... this is by design, your avatar and your viewport are separated: you can be looking at island A while your character is walking at island B.

That's rather unintuitive, and counter to the way almost all modern games do it. If your goal is to lean into the familiarity of the gaming world to teach people programming, you might want to either change that or make it more much more explicit.
