A fellow hoard survival game! Alright!
That was addicting, the game play is fun and the mechanic of using light to heal is a unique twist!
The cost to light the fires though is a little high, and it means that dropping below 25 hp is an automatic game over, might be better if you made them free but one time use, that would also have the benefit of pushing people to explore the map more, and a sense of tension/relief when you finally find a new fire!
Very fun game though, I'm gonna dive back in for another run! xD
