The page's licensing, copied here because the page can be edited later:
  "CC-BY 3.0", "CC-BY 4.0", "CC-BY-SA 4.0", "CC-BY-SA 3.0"

This game uses it under CC-BY 4.0, whose text is CC-BY-4.0.txt in this folder.
It's the only one of the four the asset policy allows: the 3.0 licenses forbid
distributing the work with DRM, and the SA ones would bind the game's own art.

The page asks for this attribution, in the author's words:
  "Produced by Julie Damsgaard/Spring Spring/Spring Enterprises @
  https://spring-enterprises.neocities.org"

That credit is in client/CREDITS.md, word for word.

Used for: assets/backdrops/arena.png, the first of the GIF's two frames at

desaturated to 75%, behind its panels.
