N-Space is an Android and iOS-based level editor and sandbox designed to sculpt indoor/outdoor 3D environments. Its interface is user-friendly and allows for rapid design and modification. This lifestyle app has a range of features that include painting surfaces with over 100 high-quality materials, creating complex shapes with the Bevel tool, and using dynamic 'substances' to design worlds with moving objects, water, and physics.

The app also includes a powerful logic system that enables you to wire components together to respond to game events. With N-Space, you can customize the sky, lighting, and fog, and experience your creations from a first-person perspective. The app has interactive tutorials that guide you through its interface and more advanced features. Moreover, you can send world files to and from other apps.

Note that if you encounter any issues moving the camera with three fingers, try disabling all three-finger gestures in your phone's settings, including screenshots, split-screen, etc. Additionally, if you experience the bug where the entire world is black, please send an email to the developer. Overall, N-Space is a great app for hobbyists and designers who want to create interesting environments to explore.
