Do you use IntelliJ IDEA for Kha development? I tried using the generated project files from the build directory, after setting up Haxe version and adding Kha as a dependency I even got the autocompletion to work, but still couldn't run the project, not to mention debugging.
Is it even possible to use IDEA? What's the IDE you use instead? I can't see myself working on larger project using Kode Studio, it just lacks too many features at the moment which I have at my disposal in IDEA (I've been using it for years for AIR development).
