This was cool! I really liked the atmosphere - the little bunker felt really cosy somehow haha. I found it a bit confusing at first because I didn't realise I needed two items on the bench, so maybe that could be added to the tutorial board's text? I was also a bit confused about what I was actually supposed to do with the objects haha - I made a dumbbell but it didn't seem to help me fighting or anything? Like someone else said, it would have helped quality of life a lot if you could hold multiple items and take them back!
I was really impressed with the overall feel and atmosphere - the particle effects and pixel shader looked really nice, and the overall vibe felt quite polished!
