Thanks so much for playing! The time rewards are actually uniquely balanced for each stage, and you noticed this perfectly with the wood during the obsidian phase! Our thought process was that obsidian is super hard to get and starts with a very short timer. Wood, being a quick resource to gather, is meant to act as a lifeline to keep you barely afloat, maintaining that intense "almost losing" panic. Every item’s value shifts depending on the stage to maximize tension — a deliberate little trick, so to speak. Looks like our emotional rollercoaster worked exactly as intended! :D
