Looks great, but why would I prefer this over say Lua or Wren? Yes, the benchmarks look nice, but not extraordinary. What is the killer argument/advantage here?
What is the use-case?
in terms of benchmarks alone languages with JIT compilers will definitely beat this, that's one possible direction to go with (there are great projects out there that make adding this capability potentially easier, MIR for example), another feature would be a C FFI rather than just a C API.
