Neat game! Reminds me a bit of Terraria. I'm impressed you were able to get so many mechanics done in a single week. Movement felt great, but occasionally the game would freeze for a frame or 2. I couldn't pinpoint what triggered it, but usually happened if I jumped too often. Also, I wasn't sure how to get the copper/iron out of the furnace. I tried hitting E to use it again and read the controls, but no success. Maybe I just missed something? Still, the digging and crafting was a lot of fun! I really liked your backstory too, made the whole environment feel relaxing. Overall, great submission!
