Nice game!
Aiming is *hard*, but it's fun to try, if frustrating at times.
The resource systems are really well-designed and fit the jam's theme quite well. Both the heat and fuel systems successfully encouraged me to think carefully about when to spend resources and when to hold them back, in a way that felt balanced and fun.
One issue I had was that it took a while to figure out how the different resources were being represented on the screen. The fuel is obvious enough, but the hitpoint/shield system took a little time to figure out, and my first 2-3 tries I didn't even notice that my character was changing color based on the heating system. I did figure it out eventually though, and it worked fine once I understood what was happening.
Also, since "time survived" is how the game is scored, it would be nice to be able to see that information during play (I did the same thing and forgot to put in a timer for my game).
Overall, great work!
