It looks nice, but F2P always bothers me. I don't like F2P games they always have downsides and usually it's because you need to "pay to win" or the developer makes no money. And a minecraft/terraria like game that did something like limiting specific essential materials would really suck.
I hope they meant that this alpha version is F2P and the game itself will be a normal buy with no microtransaction BS built in.
