Thanks for the feedback!
Sadly we can't take credit for the art assets, as that goes to Keneny over at Kenney.nl/assets. Though the other two did a solid job putting them together in pretty ways :3
Sound was my end of things, so I'm glad you like it. It was an idea i'd been workshopping for a progressive trance track, so it translated into a scaling background really nicely.
In terms of the lack of clarity on missions, we didn't get as much done as we wanted but one of our goals when we find more time to work on this a little more is to add mission icons that stick to the viewport edge when they're offscreen so you always at least know the direction you need to travel in. :)
