Absolute cash grab. I'm really disappointed. I played up to level six and it has gotten to that point it seems all clicker games get to where there is literally no way of making meaningful progression without paying. You just have to wait. And it's not even like it's fun when you are generating enough money to be progressing at a steady rate. You watch the numbers go up, then you click. You read an IASIP reference, then you click. Even if clickers are your thing, this just feels boring.
