I was surprised by this since all I need on Linux is llvm and clang, but looking at the official getting started page, it does indeed say "MSVC compiler and windows SDK" are required. Is that really the only way to run it on windows, or is that just the path most familiar to a typical windows developer?
I personally disagree with saying it requires IDE support. I want to write a ctags parser for it, but that's all I would ever use; as a die-hard vim user, I never liked all the language server stuff people are so reliant on these days. But if that's what people want to use, it's available for Odin as well: https://odin-lang.org/showcase/ols/ -or- https://github.com/DanielGavin/ols
