Nova Craft

Nova Craft runs Minecraft-style block building entirely through WebGL, which trades some of the full game's depth for something that loads instantly in a browser tab, no launcher, no install, just terrain to dig into or build on the moment the page finishes loading.

Because the terrain generates endlessly in every direction, picking a general area to settle into rather than wandering indefinitely tends to make building projects easier to return to and expand on. Digging underground for materials before attempting an ambitious sky build is usually worth the detour, since running out of blocks mid-construction breaks momentum more than a short mining trip beforehand would. Paper Minecraft offers a similar browser-based building and survival loop in a 2D format.
