Other features that would be nice: variable assignment, logic, and the ability to add scripts in some other language.
Great suggestion! I originally envisioned Oracle as an extension of perchance.org. I wanted to get feature parity with the perchance grammar. This has been mostly achieved by this Rust implementation. I plan on adding these features to Oracle next year. This would take care of variables and boolean logic.
Embedded scripts from another language is also something I thought of doing, though limited to Lua or Python for now. I am in the process of rewriting this to support Go and Lua, heavily inspired by this Slay the Spire clone which supports Lua scripting.
