Thank you for taking the time and writing up such detailed feedback!
It’s really a shame that we failed to communicate that the Irrlicht will actually lead you to where you need to go at all times. Additionally to blinding the Hafermann.
You could play it without even paying attention where you go as long as you follow the little blue light. That was the reason there was not much sign-posting going on to give a general orientation. Welp :D
