Please reread the gamepage.. 2.0 is free and 2.1+ are a one-time purchase at minimum of $4.00. You may be in a country where $4.00 isn't a justifiable price, or maybe you just can't afford it, but if you are American, It really isn't that bad of price for a game of its popularity
I never said it was a bad price? I'm downright broke as I'm only 16, and I rarely ever get money to buy online items. So I'm glad I got to get it beforehand.
If you're talking about having v2.0.1, that build was a mere bug fixing build. 2.1+ are gonna cost $4 so you technically didn't get it beforehand as it had costed money as soon as the build was released
