Geting it today!!!

Yes I believe it's worth it I'm just waiting for there to be animals and monsters.

Sounds great Please keep always in mind that buying the game now in alpha state also supports development. Of course the game still lacks of some important things, but we're working tirelessy on it.
And if there is anything in the game that needs to be changed in your opinion, simply tell us. We're glad to receive feedback and suggestions, and we do our best to fix bugs as fast as possible.

About animals: That will be the next big update when the current one about the extended construction system is finished

Your hard work is becoming obvious.
