Hello an actual someone who have made flappy bird look a like, it's actually not that hard to make if you just doing it as a side project you pretty much can make it in 3-5 days, and if you just doing it fully you can do it in 1-2 days
Why not use a DxD anime trope and turn the MC into the reincarnation of the hero from the past that he represents, so the novel has more action and the MC has powers so that nobody wants to screw him in the future.
Thanks for the chapter[img=update][img=update][img=update][img=update][img=update][img=update][img=update][img=update][img=update][img=update][img=update][img=update][img=update]
