This is a fairly well made game and very enjoyable to play.
The only thing I found especially troubling as a design choice is the "agile red" achievement. The reason being the randomness of the spawn can often make it impossible at no fault of the user. I have had on a number of occasions been dropped directly onto a lava tile. One way to mitigate this would be an optional item which provides early detection of enemy units as the counterpart to the H2 hull.
For those who are having trouble with it: being shot by the lasers does not count against this achievement, just hitting the physical base. I ended up using H4 for slightly smaller size with high vision and agility, paired with the S1 (radar).
