It's a hack that gets better as you go. It kinda gets meh around 8th badge but it's still fantastic and despite the need for polish it's definitely set a new standard for hacking, and probably more of a standard than Unbound set.

Some flaws:
-The music needs WORK. The new compositions are fantastic but do not reach their full potential -yet-
-Glitchy af
-At times I feel there needs to be more direction, but that might be a me problem

More great features:

-Follower Pokemon, which i always love.
-Multiple outfit choices that you can buy, and a portable PC you can earn
-You can get Lucky Egg and EXP.Share early, which can help diversify the difficulty of the game other than Normal/Hard mode
-Reasonable side quests

Favorite features:

-Stardew Valley fishing mechanic, it's nearly perfect.
-A lot of NPCs shown playing with their Pokemon, and lots of Pokemon walking around in the overworld, making the region feel alive
-The region feels big and the routes are designed unlike any other Pokemon hack i've played

It's faithful in the way in which is doesn't alter the energy or the feel from the original game much at all. There are a lot of hacks that add certain things that make it feel like a totally different game, but this one feels like the best version of Crystal is could possibly be.

(My bad this seems to be version 3.1.0)

Speaking of which, what are your favorite Pokemon hacks/fan games?

Hey!

I'm queer, disabled and struggling to draw consistently, but I made this for last year's Star Wars Day and it's still the piece I'm most proud of
