Graphics are simple and blocky. The main mechanic in Blocky World 3D: Creative Mode! is that you have unlimited blocks and can fly around easily to build whatever you want. i found that the creative mode lets you place and break blocks without worrying about survival or gathering resources at all.
Moving around is easy with basic keys. You use WSAD to move and Space to jump. Sprinting is done with Shift, and crouching uses C. For interaction, Left mouse button mines or destroys while Right mouse button places a block. Press E to open your inventory, Tab for settings, and F to activate flight mode. Z and X change your height when flying, which is handy.
Inside the game, you press keys to do things. To move, you use WSAD and Space to jump, which is kinda weird anyway. C lets you crouch and Shift makes you sprint faster. For building, you use the mouse buttons to mine or place blocks. E opens your inventory, Tab accesses settings, and F turns on flight mode. Their are controls for height with Z and X. i use these to build high up.
Quick tip i discovered is to use flight mode for better building. It is better then walking everywhere. Press F to fly and use Z and X to go up or down. This helps you see your project from above and place blocks easily. The infinite world has biomes like Meadows and Snowy landscape. Day and night cycles and weather like rain or snow happen. i like to build castles in the Black forest biome.
Placeholders are a thingy i need to mention. The game has a creative mode thingy where you don't need to survive or manage stuff. You can build and destroy unlimitedly. Flying is a mechanic activated with F, and you change height with Z and X. There are biomes like Meadows, Black forest, Swamp, Snowy landscape, Plains, Ash lands, and Far North. Weather includes rain and snow, and there is a day and night cycle. You can build homes, castles, cities, or test ideas with dynamite for experiments.
