I really liked the risk–reward system in the game. You can explore freely, but if you die, you lose everything you’ve collected. That creates a nice balance and tension.
One idea for improvement could be to give some progression tied to the base. For example, bringing something back to the base could unlock new abilities for the character. Even a small upgrade system would add more depth — maybe when the base levels up, the light radius in the darkness expands, or when you die, you lose fewer resources.
Aside from that, the game already feels very polished, clean, and enjoyable. Great work for a game jam entry!
