- Visuals: Great! Crisp, accessible, feels like I know what info I have through a quick glance after the tutorial.
- Sound: Nice loop with the song, but I do think the sound effects clashed with the abrasive drum and guitar. May want to either lower the volume of effects or the music?
- Engagement: Loved it. Gave it a couple tries, I wasn't sure if it was getting more difficult over time or if I was slipping up. It does feel like there's not a lot of incentive to move away from the center - my highest score was when I just stood in place on top of the drill and focused on aiming rather than flying around.
- Spectator Appeal: Think this would be a great game for a crowd! You have the tension between your health bar and hunting for resources on a timer. I would agree that maybe some iconography for the fuel squares could help people "read" quicker on what's happening. Without the tutorial, it's not really clear.
- Ease of learning: While the tutorial does give you a baseline understanding of what the player is looking at, I did feel a bit overwhelmed when I had to get moving. A smoother ramp up period might be helpful here, because everything is somewhat thrown at you at once. After I got the basics down, it was a nice balance of resource and health management.
