Thanks for playing and providing feedback! Also, great job on 4 minutes, not an easy feat! There is a mechanic in the game that when the pests grow more ferocious (every 30 seconds) a fuel pick-up is also spawned somewhere on the map. So, if you run out of fuel and can survive long enough you will have a way to refuel. I agree the player movement needs a little tuning up. I'll also look into your other recommendations.
