Great work for your first jam! The art is very good. The game definitely needs a rebalance imo. Campfires are effectively useless because you never know if they'll blow up on you and wipe out the rest of your energy. The best strategy seems to be sticking around the tent and spamming E since every time you enter the tent, you gain a little energy. I was able to face tank enemies and stay topped off this way lol.
Good luck to you as you continue your gamedev journey!
