Hello, hello, SighingSlider.
Thank you for playing SPIEGEL EI. I apologize if you find any trouble within the game. The hints themselves are actually like that in the original version. I'm just a translator, I didn't do anything to change the hints unless the dev themself asked to do so, the dev intentionally made them slightly vague to make it harder to solve. Just like what you say in your video, the game relies heavily on environmental and visual hints, it may trick you or it may help you.
