How exactly do I get this game into Fullscreen mode?

Is it really that bad? It looked okay on the Vita coming from someone that's not a huge crafting genre (Mineycraft/Terraria) fan.

Or was the game abandoned?

Why can we only change 4 of the controls? why are the controls seemly mushed together on the left side of the keyboard? it is uncomfortable to play when nearly all your buttons are on one side of the screen :/ That and you cannot change the window-size of the game so some of it I cannot even see :/ Otherwise how are those who can use the controls well liking the game?...

is this terraria
