The concept of delivering in the universe by worm holes is really cool.
But it can be depressing while looking for the destination of delivery.
Without a clear indication for the planet makes it a hardcore game.
And since it's a space game, the music not really fits the tone.
Besides that, I think the gameplay is just fine, the content is expandable.
It could be really fun to get some cool upgrades and abilities on the road of becoming the best delivery service in the universe.
