Very cool theme and concept! I didn't really need to bother checking temp/fuel for the first few levels but then I exploded randomly, checking the bar I had overheated! I liked how the higher levels mostly required more focus on those resource bars and had more sophisticated layouts. I also loved all your particle work, particularly the stars in the background! Styling of your itch.io page is so fun and on theme and I enjoyed your game very much overall! Oh and how your font is visualized in game is fantastic!!
A few bugs/things I noticed: I found the looping point on the music to be really noticeable after a bit which I felt was distracting and the game by default was pretty loud!! I think the levels need to become checked off or change visually to indicate they've been completed as I accidently clicked on the same level a few times! I also found a bug where if I rapidly pressed a variety of w, a, s, d while on a 'battery' it would give me 2 or even 3 thus completing the level!
Once again though, amazing work! Thank you for creating such a fun, creative game! :D
