Well, having only one romance may be an issue - honestly, it really depends on how it's done, so yeah... In this case, I really like it!
And yay for bad endings! I'm writing my own game too, even though it'll have all gender romances (choice between a male or a female MC, and all gender options for both), but I'm also putting a lot in the overall plot and bad endiiiings! Bad endings are so fun to write haha
