It's a cool game! Getting max fuel to win the game doesn't seem to fit well (at least not for me). I would have enough fuel to shoot a couple bullets, kill 2 enemies, and repeat. If I ever got shot I would spend a while roaming the map looking for fuel. I loved the variety of enemies! The amount of enemies that came out over time was good, any more would be way too much. I liked the concept of staying close to 'base' to shoot. It's a fun game, good job!
