Thank you! I actually haven't played that game before, I'll have to check it out!
Hmm, it could be you died of cold, you can use the torches and/or get indoors to get warm enough and the frozen damage will get healed. Or could be you didnt have enough crafting materials.
In either case, the health/freezing system needs work for sure. I can see it not being obvious how to protect yourself from the cold in it's current state.
Also I plan to rework the crafting system. There is a little recipe display in the UI above the torch/medkit/bomb but it's probably not obvious how it works right now.
