It's not really a bad game, it just doesn't have anything special.
You upgrade a few things (the reactor and the mainframe), then you go to another window to click on some static shiny objects, and that's pretty much it.
Sadly, I really thought there was more to it. When I first went to the rift screen, I was presented with a window full of fog, and I thought I was going to explore a map or something, but no, you just have to click some mini targets and collect shiny beads.
On the other hand, the art is really good. Even though it's mainly just UI elements and fog, it still conveys a good sense of exploring some random planet. Unfortunately, the gameplay is very simple and generic, and it doesn't offer anything particularly exciting or interesting to do.
