Really cool. The moment I realized the other planet also had their own skill tree, my mind was blown. Such a nice experience.
I kinda expected the controls to be based on where you're facing, so I needed to get used to it.
The missions were a nice change of pace, but I felt kinda weird getting a score multiplier on planet damage, since that basically only happens during missions and not in normal gameplay.
Maybe it would also be nice to be able to deactivate the drone. They often shoot away the black asteroids, which is annoying.
Really cool game. You should make it a full Steam game.
