Feature Comparison
The situation of GUI features and capabilities on 1 June 2026 is the following:

- "Over 23000 base tiles" means that GnollHack has over $23000 \times 64 \times 96$ pixels of custom tile graphics. That's over 138,368,000 pixels, which means over 16 full 4K screens of custom tile graphics. Some of these graphics are auto-generated, such as statue graphics, by our custom Tile Set Compiler. Animations also take up a lot of space.
