This is BRILLIANT!
THIS is what I want to see when I play a game jam entry. Something new, different, unique, creative, immersive... I always felt like being in that elevator, avoiding the lizard and looking at the masked creature in the eye. It's crazy what people can achieve with just a couple of sprites and good sound and atmosphere.
Oh and I never understood what I had to do with the fire, I guess clicking or dragging but it always ended up killing me so I don't know.
Still, great job, loved it.
