Main features

• Realtime Preview: the biggest feature in Light.vn. open up your project in the editor and click on a line - the preview screen immediately displays the state of the project at that point in time.

• Games in an instant: Unlike drag and drop UIs, Light.vn's scripting language allows you to simply copy-paste your scenario, your first game is done in an instant.

• Pixel perfect: Feel free to finally get that textbox, that image just right up to the very pixel. No need to restart the game or click refresh - Light.vn's editor auto reflects on preview your every single change

• Complete UI set: Backlog, Config, Save, Load, Replay, etc. - Light.vn's official sample comes with all built in, ready for use. 

• Simple: Your whole project is just a single folder. Copy paste to backup. Double click the editor to go again. No need to install some central bulky program on your PC.

• Extensible: From traditional visual novels to 2D RPGs and 3D dungeon mechanics, unleash your possibilities. 

• Well Tested: Tired of software that breaks now and again? Light.vn comes with it's own testing suite, LightTests.exe, guaranteeing quality, stability, and deterministic performance.

• Completely free: We take no dime. (And have taken none since development start in 2012)

• Great support: We've worked with teams both small and large for over 10 years. Have a question? Just drop into Discord! We have your back.
