Thanks!
There are dozens of locations in the kirby games (and honestly I don't recommend the anime since it barely follows the games at all), well enough to give brawl a run for its money.
Some of the stages would obviously be the ones from Smash (minus Great Cave Offensive, that one is getting reworked into something actually playable), the stages from Kirby Fighters/Fighters Deluxe for the 3DS except reworked a bit to fit better into the Smash Bros aesthetic, and plenty other stages directly based on the games. (The anime is only getting Dedede's Castle Hill/Cappy Town in the same slot, specially since the other locations from the anime could easily be replaced with stuff from the games)
The game runs on the engine of another Smash fangame I'm collaborating with: Smash Bros Lawl (I have a topic for that in this same forum), which includes a character/stage maker. It's kinda like Mugen but in Smash. I'd take care of programming everything into the game.
That's... actually how the original plan went, maybe I made a typo somewhere and you mistook what I meant to say... don't worry about it, Strong is gonna be the Melee one with Weak being the Brawl one, don't worry
