You absolutely can! The next update will separate the friendship and romance routes more clearly but even now you can have a non-romantic playthrough without missing any important (non romantic) content.
Oooh, friendship routes :O I look forward to that :D I'm really liking the options so far, especially the mental health representation ^^ At times, I just have to stop and take a deep breath and hold back tears, it's that well done! Looking forward to future content :)
