[Brwser][PC][2016-2019] Weird unfinished MINECRAFT-TYPE voxel game with no HUD and pastel textures
I remember a browser game I used to find on hispanic flash game sites around 2016-2019. It was a first person 3D voxel/block game but it had almost nothing in it. No HUD, no menus, no inventory, no music, no enemies, no tools, no crafting, no guns, no objectives, nothing. You could only walk around with WASD and destroy blocks permanently until reloading the page. You could not place blocks.
The world looked infinite and had weird cave-like terrain with blocks above you like giant open caves. The textures were not minecraft grass/dirt/stone textures, they were handmade looking pastel textures with soft colors like purple, cyan, green, pink, etc. The sky also had a weird underwater feeling. The game looked unfinished or like some prototype/demo someone uploaded. It loaded instantly in the browser without intros or logos.
I attached a drawing of how I remember it looking.
