Users who have helped edit sprites for use on the site in the past or present (shiny/back sprites):
All The Players, for all the feedback and suggestions, and sharing this with friends :)
For development, I've used gedit, Geany, Sublime Text and VSCodium text editors for writing code. GIMP was used for any image-editing. The maps currently being used were made with Tiled. Sprite variants are made with Phatch. We use Gitea for code hosting and version control.
We also use the following Libraries on our website: AmaranJS, Bootstrap, Chart.js, fixto, history.js, html5shiv, jquery, jquery-ui, jquery.scrollTo, jquery.confirm, jquery.timers, countdown, lightbox, Tablesorter, ie7js, selectivizr/ie-css3
