Underrun — licença
==================

Underrun é um jogo de tiro com visão de cima, em WebGL, de Dominic Szablewski (phoboslab), feito para a
js13kGames 2018 (o pacote inteiro precisava caber em 13 KB compactado). O repositório do autor
(https://github.com/phoboslab/underrun) traz a licença MIT em LICENSE.md, reproduzida abaixo, com o aviso
"Copyright (c) 2018 Dominic Szablewski"; conferida no commit f933e29152d7fc1ca61d4b3eaa8b29551d7d7a62 (o
mais recente, de 12 de outubro de 2018). O README diz (texto original):

    MIT Licensed

    Please be aware that this projects makes use of the Sonant-X library (albeit heavily modified)
    which is published under the zlib license.

Música e efeitos sonoros: segundo o post do autor sobre a criação do jogo e os créditos do próprio jogo
("Music: Andreas Lösch - no-fate.net"), foram produzidos por Andreas Lösch. Eles ficam no repositório
(source/music-dark-meat-beat.js e source/sound-effects.js, dados para o sintetizador). Perguntamos ao
autor no GitHub, na issue "Licence of the music and sound effects"
(https://github.com/phoboslab/underrun/issues/14), e ele respondeu em 15 de outubro de 2026
(https://github.com/phoboslab/underrun/issues/14#issuecomment-6187878083), texto original:

    "Music and sound are part of this repository, so yes: also MIT licensed."

Gráficos (os PNG de m/: textura e mapas das três fases) e código são do autor.

O que este site serve: index.html e m/q2.png, m/l1.png, m/l2.png, m/l3.png do zip que o autor enviou à
competição (https://js13kgames.com/games/underrun.zip, SHA-256 79f82b8a...a837cc0), sem nenhuma
mudança. Os quatro PNG são idênticos byte a byte aos do commit f933e29; o index.html é o código de
source/ minificado pelo build.sh do repositório.

O sintetizador embutido é o Sonant-X, de Nicolas Vanhoren (fork do js-sonant de Marcus Geelnard e Jake
Taylor), reduzido e modificado por Dominic Szablewski, sob a licença zlib. O aviso de
source/sonantx-reduced.js no commit f933e29 está reproduzido abaixo.
