I find this game to be very poorly designed. To do well in the game you must wait, you must wait a monstrous amount of time. The way the game works now upgrade points are spawned now and then, if you let an asteroid fly around for a long time the upgrade points will still spawn. To get past level four even, you need upgrades. The only way to get upgrade points is via the upgrade points that spawn randomly. A better system would be that the faster you complete a level the more tokens you get. That way you aren't incentivized to wait for so long, the game will get more exciting. I understand the upgrade system may not be the core aspect of the game, yes there is some hidden story in that each planet has a letter hidden, combine the letters you get a story, but this is locked behind getting to new levels, and it is a very arduous task.
