Thanks so much! It's awesome that you had such a fun time with the game so far!
And to answer your question: yes, there will be two romance options, and each one will a couple endings. There will also be multiple endings that don't have romance - so your choices will shape both the plot and Stan's love life. We don't really believe in the idea of "bad ends" either, so all of them are totally valid conclusions to the story (though there is one that cuts things a little short).
It'll be exciting to see what endings people gravitate towards in the full game, they really cover a whole spectrum of possibilities!
