The one thing that caught my eye in this hack was the storyline, which to me seems very original, while other hacks have always mainly been based around a legendary, you have incorporated great twists in the game but also left a cliffhanger with Celebi becoming involved as well! So I'm hoping that the events in this game are thrilling and always making us wonder what the bigger secret actually is.
While I'm not a fan of the minimal changes to tiles, I do like how you're adding new battle backgrounds and I also like the text, big fan of it.
I hope the hack lives up to the expectations set for me in the introduction and features section, and I wish you good luck!
