This game is about Pride (and given the rainbow flag, I assume with LGBT pride and pride month). However, it doesn't really talk about that in the game at all.
Instead, there are six paths, each corresponding to one letter in 'pride' (and an exclamation mark). Each of the letter paths has part of a hidden message that unlocks a final message.
On the letter paths, there are copies of the letter that you are currently learning about, each corresponding to a positive word, like Respect or determination.
However, all of the connections are really tenuous. The words don't have anything to do with Pride specifically; they're just describing positive traits in generic terms. It could equally as well be Pride in your local grocery store, patriotic pride, religious pride, pride in rehab, etc.
I think it might have been neat to tailor the message more to the theme.
