Great but...
Mouse control only is a crappy limited way to play, better to have an option of the keyboard or mouse.
Also there are points where all the ships are spamming so many bombs its difficult to avoid even with a super small body with high speeds.
Lots of difficult in maneuvering in close quarters if you suddenly get netted while boosting to attack. Also notice that the size and regeneration really dont help when you're being pursued by submarines that fire way too many missions.
Oh love the bit of the bite of the moon achievement, but yeah got up to maybe wave 20 or so till the boats spammed so many water mines.
More improvement on the controls.
