I am proud to announce that cake.sun is now public!
To keep this post short and not repeat myself, all info can be found here (please give me a star btw 🙂 ) https://github.com/CakeEaterGames/sunscript
Sunscript is a custom language made specifically for Hackmud that will allow you to write complex filtering logic with very short and simple code. No more chained else if statements! Only Short Upgrade Notation. Only SUN! ☀️
I encourage you to NOT use #fs.cake.sun
but to download the compiled code! 
If you just want to play around, here's a web based interactive language demo https://cakeeatergames.github.io/sunscript/
I have finished my first Sunscript file that picks the price for all my upgrades and decides what should be culled / sold / kept https://github.com/CakeEaterGames/sunscript/blob/master/samples/megafilter.ss
A user @solemn pier helped me a lot when testing the language and together we found most bugs. They said that they have successfully integrated the language into their workflow. I encourage you to do the same!
If you have any questions or suggestions, let me know.
Have fun, mud!
