I find it difficult to gauge enemy strength because the meters do not line up as you go from friendly and enemy asteroids. The icons for Tree and Missiles are not on enemy asteroids so the gauges do not line up.
Possibly change the alignment of the sub menus so that it would be easier to compare strengths. Or, if you select a friendly, and hover over an enemy, it shows their strength in an overlay to your graph.
Quickest fix (I think) would be to simply add a solid line down the center of each value with small tic marks at equal intervals. Should be easy to implement and would be the same for all.
Other than that, great game so far, played the original, hoping that this one is longer
