## Scope

This license applies to:

1. **Bundled Assets**: art, tiles, chipsets, character sprites, portraits, effects, sounds and music that the
   licensor ships with OPRN Studio, except third party assets listed in `public/assets/ATTRIBUTION.md`, which
   remain under their original licenses; and
2. any asset that its rights holder publishes in the OPRN Asset Store under the "OPRN Game Use" (`OPRN-GAME`)
   license. For such an asset, "the licensor" means that rights holder.

## Grant

The licensor grants you a perpetual, worldwide, non-exclusive, royalty-free license to use, copy, modify and
adapt the assets, and to distribute them as part of games and interactive works you make ("Your Games"),
commercially or non-commercially. You may also use them in screenshots, trailers, store pages and other
material that promotes Your Games.

## Limitations

1. You may not distribute, sell, sublicense or share the assets, in original or modified form, on their own or
   in a way that lets others use them separately from Your Games — for example as an asset pack, a tileset, a
   sprite sheet collection, a template project sold for its assets, or an upload to an asset marketplace.
   Files packaged inside a game in the normal course of distributing that game are not a violation, even if a
   player could extract them.
2. You may not claim the assets as your own original work, or register them, or anything substantially derived
   from them, as a trademark or design.
3. Required credit lines, if any, must be kept. The editor adds them to exported games automatically.

## Persistence

Rights you obtained for an asset are not withdrawn if the asset is later hidden or removed from the editor or
from the OPRN Asset Store, as long as you keep to these terms.

## No Liability

As far as the law allows, the assets come as is, without any warranty or condition, and the licensor will not
be liable to you for any damages arising out of these terms or the use of the assets, under any kind of legal
claim.
