Very cool game :) keeping the friendly fire makes the choice of which monsters to attack really interesting. The atmosphere with the pixel art and music is also well done, the fire dimming out is also a nice mechanic to make it harder as time goes on. The art is nice, I just wished the ennemies were a bit more visible against the background I had a little bit of trouble seeing them pop up sometimes, but it's a nitpick.
Congrats !!
