I did play it, it was short enough.
Naturally the story is charming even if both characters are women. I like their personalities and backstories even if it's not my preferred coupling. I can imagine it being difficult to write those backstories for males.
But yeah, I'm cool with whatever you make, even if I pass based on the subject matter sometimes. It would certainly expand your fanbase if you do more than just BL. Nobody can fault you for that, especially if you simply want to make those games.
(Because spoilers, I put this at the bottom)
The twist I saw from a mile away, but there were many hints. I feel more sorry for Cynthia's father honestly, because she can never take back what she said and he has to live with the guilt of pushing his daughter away and thinking she left while hating him. Meanwhile, since she still regrets her last words, she and Lynette can stay together. Unless her disappearing at the end was meat to symbolize her moving on.
