There are some bugs that I think can and will be fixed, even if it takes longer than some are willing to wait. But I think the mechanics of the game itself are just fine as is - that's just me personally, I know a lot of people think the game is awful and tbh I am not sure why they still play in that case. I love this game!
Of course, I'd love for there to be more in-depth personalities, zodiac compatibility, and a wider variety of emotions... but the lack of those things never weigh on my mind while I play. The only thing I ever got frustrated over not having in my game was the pool tool. But they added that, and I've lived on and played happily ever since. I love the addition of new free content, and paid content as well (though I wish it wasn't so expensive).
Overall, I don't think the game needs "fixing."
