Sorry for the wait. The game is now in a state I'd consider sell-able, although it's still pretty early in development. Now is a great time to buy the game if you want to be actively involved in development. If you just want to play the game, you might want to hold off until it's more complete, but many people find it fun in it's current state anyway. In either case, I recommend reading the Early Access section on the store page for a more complete description of the game's current state.
