In the top Hud the player can see constantly the two main objectives of a space mission: DV and time of flight. They both should be bars increasing from 0% to 100%. At the moment ,one is increasing (tof) and the other decreasing (DV).
An alternative would be to visualize both resources as decreasing. This second option could have problems in the future where levels could not have a maximum DV or tof defined.
