OlamREEE (three e's; pronounced "oh-lahm REEEEEE") was made by Sean 0 year(s) ago, the same person who made UGWA and posted surviv.io on Schoology.
This web app is open-sourced on Github; you can submit bug reports and questions there as issues or as emails to seanthesheep22+reee@outlook.com.
Colour gradients to show melting points were made possible thanks to chroma.js.
Live editing was made possible thanks to TogetherJS.
