The red bundle is part of a puzzle. The know-how not necessary. But you can do more with a TShirt than just wearing it.
T-shirt has been re-used quite a long time ago already 😄 I have been even more eco-friendly in Chapter 3, near the big hole - but I used even that already - and my only remaining container is green, and nowhere to make it transparent, except for myself which is not healthy, so I could recycle.
I've also tried to create a medieval flashlight - in hope for some critical fears - or something - but looks like a no go.
I guess I just made too much mess 🥲 (because I've realised that I can actually run from brown triple-K only after I've wasted all my health and warfare - should have read Page 10 more throughly before playing the game 😅)
