Neat idea to link health and fuel. Reminded me of Metro 2033 where special bullets could be used for more damage or as currency. My main complaint was the character would stop when colliding with walls instead of sliding and would slow down when walking up stairs. Also, I'm not sure I'm able to beat the boss. They kept spawning more little enemies and I collected all the fuel but kept running out. Eventually I was completely swarmed, lol. Overall, really impressive visuals for a game jam game! :)
