Seconding this; act has a lot of potential but misses a number of features such as support for deployment environment variables (eg `${{ var.DEPLOY_SPECIFIC_ENV_VAR }}`) and only recently added support for reusable workflows (https://github.com/nektos/act/issues/826). It looks like fine software and the maintainers deserve praise for their work but it's not yet a drop-in replacement for GitHub Actions.
