    I created a small 2D game about an ant▲89

    Hello everyone! I created a short game in just a few days, just for fun, where you play as an ant and feed it apples This game also features random landscape generation, with clouds and trees arranged in a chaotic pattern across all coordinates. This is what took me the longest time :) I would appreciate your feedback ^ ^

    AI-native browser game that users can craft unlimited 3D items▲32

    Most games have limits. You can only use preset features, need coding for customization & adding mods, require expensive extra devices. We wanted to remove those barriers. That’s why we are building space zero—a browser based 3D world powered by AI. We plan to build players can freely mix items to generate unexpected creations with unique properties and sounds. Also the world itself is dynamically generated, evolving endlessly. I uploaded a demo version I’ve been working on for the past month! I hope to get any feedbacks or comments :)
