You are free to:
Share — copy and redistribute the material in any medium or format
Adapt — remix, transform, and build upon the material

The licensor cannot revoke these freedoms as long as you follow the license terms.

Under the following terms:

Attribution — You must give appropriate credit, provide a link to the license,
and indicate if changes were made. You may do so in any reasonable manner,
but not in any way that suggests the licensor endorses you or your use.

Proper attribution is satisfied by preserving the following existing elements,
where they are present:
- the original game credits displayed on the intro or title screen, and
- the original in-game links to the official project repository and website.

If these elements are not present due to technical or platform limitations
(e.g. alternative engines or ports), attribution must be provided in a
reasonable and visible manner appropriate for the platform.

When distributing the game, you must not present yourself as the original
author or imply endorsement. If accepting donations, it must be clear that
they are not on behalf of the original authors unless explicitly authorized.

NonCommercial — You may not use the game for commercial purposes.

The following sections provide clarifications and additional permissions and do
not limit the rights granted under the Creative Commons BY-NC 4.0 license.

Commercial use (not permitted):

The following are considered commercial use for the purposes of this license:

* distributing the game for a fee,
* adding in-app purchases, subscriptions, or paid features,
* including advertisements or monetization mechanisms within the game,
* using the game code or assets to train machine learning or AI models
  intended for commercial use, or to create datasets for such purposes.

This does not apply to ordinary use of AI-assisted development tools by end users
or developers, where the game code or assets may be processed as part of normal
development and are not deliberately collected or used for training datasets.


Allowed uses (not considered commercial or explicitly permitted):

* creation, distribution, and monetization of user-created PK2 episodes and other
  user-created downloadable content, provided that the game itself is not bundled
  as part of a paid product,
* gameplay recordings, videos, reviews, and live streams, including monetized ones
  (e.g. via ads, donations, or subscriptions).


Additional permissions:


Non-commercial redistribution of the game through free and open-source
software distribution platforms (such as Flathub, Homebrew, Winget,
or Linux distribution package managers such as APT, DNF, Pacman, or Nix)
is permitted.

For clarity, this includes distribution where:

* the game is provided free of charge,
* the game itself is not monetized (e.g. no in-app advertisements, in-app purchases, or paid access),
* proper attribution is preserved.

Exception:

Notwithstanding the NonCommercial restriction, Janne Kivilahti,
SaturninTheAlien, and Danilo Lemos are explicitly and independently permitted to distribute
compiled versions of the game on commercial storefront platforms
(e.g. Steam or Google Play).

This permission applies only to the above individuals and does not
extend to other parties.


Dual licensing:

The original authors (as listed above) may grant additional licenses or
permissions on a case-by-case basis.

If you intend to:

* sell the game,
* generate revenue from it in any form (excluding explicitly permitted uses such as
  user-created episodes, gameplay recordings, or live transmissions),
* or distribute it in a manner that does not comply with the terms above,

you must obtain prior permission from the original authors.
