How Grimsonland Works
Grimsonland is built with web technologies and delivered through this page in an embedded frame. When you press play, your browser downloads the game's code and assets — a few kilobytes to a few megabytes — and runs them locally at full speed. All the processing happens on your own device: input goes straight from your keyboard and mouse to the game, and rendering happens on your GPU. That is why browser games like Grimsonland start instantly and feel just as responsive as downloaded ones.
