It's supposed to be expensive, maybe build more ore tanks? I nerfed the material value in v1.3.3 which should reduce the cost of kyrium (and others) too.
When you have enough money or level you can go to points guy. When you press the arrow,you must wait. Then next arrow will appear and... you can spend all cash to points! 10000-15000$=2 points.
It's a temporary universe created when fighting the boss, but the game seems to have failed to get rid of it for some reason.
