Looks cool, but I'm sorry to say that it wasn't very intuitive for me, I only tried a few times, but honestly I have no idea how to affect my survivability...
Thanks for feedback. I think I'm gonna work more on it to actually make it fun and have proper tutorial/help explaining the mechanic. It's really simple, you loose heat while moving and gain heat from the other enemies by jumping on them, you also loose heat when they jump on you. If heat reaches 0 you die, but it's only encoded visually, blue = 0, red = 1 :)
