I don't know where to start, i think by the fact that i was driven to create this account just to be able to comment here.
I finished playing your hack a few days ago, and man i can and i must say that this is easily the best hack i have ever played (not that i have played that many before, I'm kind of new in this world)
First, I must say i didn't come across any bug nor anything looked out of place, this really looked like a legit game, something that game freak could have developed somewhere in a parallel universe.
The difficulty was ok, not too hard but challenging enough, and the way the game starts in the first mission, getting totally destroyed by Red really made me feel like a true (useless) rocket grunt, like i was really seeing the original story through someone else's eyes.
I think the narrative was good enough, i don't expect a full visual novel-like narrative in a pokemon game or hack, but even with that the story trapped me, i wanted to know what was going to happen next, this had me in the edge of my seat almost in every moment after Giovanni's revelation about the war, and that "catastrophe" thing and what was seen in oak's secret lab... Oh boy, it was all too bizarre but at the same time fit perfectly.
Absolutely loved the OSTs made for this game, and i would be lying if i said that i don't want a sequel, even if i have to wait others six years or even ten, I'm sure that if a sequel came to be true, it would totally worth the waiting.
Overall, amazing hack,it has my 10/10, you did a great work, i congratulate you and everyone who could have helped in this project, we don't deserve you but there you are, thanks.
