To be honest to the end, the code is not the only thing that is needed for a mobile game. You can do everything perfectly, but it will not be popular with your target audience. Need an idea. Something that grabs attention with a new twist on the plot. I would recommend reading these reviews from Logi on avanda.id . As you can see, the plot of games often has a basis from past versions but is revealed from an unexpected side. I only pay attention to these games.
