I have some qol suggestions: make the fonts bigger(maybe i am just on a hangover but anyway) and a "line" tool like you click on someplace and another place and you get a line of blocks there. Also a way to skip the simulation. like "okay after 2 seconds i can see that this design is a piece of shit, let me out of this". Another thing i thought of, but there is no air here, right? so we couldnt have airlocks or something like that
