SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
-----------------------------------------------------------

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.

The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded, 
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.

DEFINITIONS
"Font Software" refers to the set of files released by the Copyright
Holder(s) under this license and clearly marked as such. This may
include source files, build scripts and documentation.

"Reserved Font Name" refers to any names specified as such after the
copyright statement(s).

"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).

"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to a
new environment.

"Author" refers to any designer, engineer, programmer, technical
writer or other person who contributed to the Font Software.

PERMISSION & CONDITIONS
Permission is hereby granted, free of charge, to any person obtaining
a copy of the Font Software, to use, study, copy, merge, embed, modify,
redistribute, and sell modified and unmodified copies of the Font
Software, subject to the following conditions:

1) Neither the Font Software nor any of its individual components,
in Original or Modified Versions, may be sold by itself.

2) Original or Modified Versions of the Font Software may be bundled,
redistributed and/or sold with any software, provided that each copy
contains the above copyright notice and this license. These can be
included either as stand-alone text files, human-readable headers or

binary files as long as those fields can be easily viewed by the user.

3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the corresponding
Copyright Holder. This restriction only applies to the primary font name as
presented to the users.

4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
Software shall not be used to promote, endorse or advertise any
Modified Version, except to acknowledge the contribution(s) of the
Copyright Holder(s) and the Author(s) or with their explicit written
permission.

5) The Font Software, modified or unmodified, in part or in whole,
must be distributed entirely under this license, and must not be
distributed under any other license. The requirement for fonts to
remain under this license does not apply to any document created
using the Font Software.

not met.

利用条件

このサイトでゲームを無料で遊び、ゲームのページや部屋コードを共有できます。Pineapy Games が権利を持つゲーム素材、画像、文章、ソースコードを、許可なく転載、再配布、改変して配布することはご遠慮ください。

Three.js、PeerJS とフォントは、それぞれ上記のライセンスに従って利用できます。このゲームの利用条件によって、それらのライセンス上の権利は制限されません。

オンライン対戦・アクセス解析

フレンド対戦

オンライン対戦は PeerJS と WebRTC を使用します。接続のために公開 PeerJS サービスを利用し、接続後は対戦相手との間で名前、部屋コードに対応する接続情報、入力、位置・向き、試合状態、リプレイ、再戦の合図などをやり取りします。フレンド対戦の部屋コードは、参加させたい相手だけに伝えてください。

名前、音量、マウス感度は使用中のブラウザ内に保存します。アカウント登録やオンラインランキング機能はありません。公開 PeerJS サービス側のデータ保存期間は、このゲームからは指定していません。

アクセス解析と外部への接続

ゲームの表示には Three.js と PeerJS の配信元、Google Fonts に接続します。公開サイトでは Cloudflare Pages の Web Analytics を使い、訪問数とページ表示数を計測します。配信時に Cloudflare の計測スクリプトが挿入されます。このゲーム独自の試合結果やランキングの送信は実装していません。
