Great job on this mod! I've been fighting for Ridley ever since Brawl was announced, so you can imagine how ecstatic I am to finally have a playable version that isn't too big, or disgusting, or modded off of Charizard. He feels and plays almost exactly how I imagined him, and I'm really happy with the work you've done thus far.
That said, I feel like he's still a bit broken. There are several moves that I think need more work.
His down air is way too safe. It goes through platforms, can combo off itself extremely easily, doesn't take much effort to aim since it's straight down and so fast, and it doesn't even leave him vulnerable if you fail to land it since it bounces him to safety.
If I could make a suggestion, I would say that you should put it on an angle, like Sonic or ZSS's down air. Have it only bounce if you land the tip perfectly on your opponent. Otherwise, just have the blade deal a small amount of damage and knockback, and have a crap ton of landing lag if you miss completely, just like every other move of it's type. He does jab you diagonally in ZM, so it's not like it'd be a completely random move.
- Alternatively, you could just slow it down, or remove his ability to bounce on the ground if you miss, but you really should take away the ability to hit through platforms. I know that's not completely canon to the games, but balance should come before accuracy if you're trying to make a viable character.
Secondly, I personally don't feel like his fireballs should last forever. Their slow speed and strength already serves him with a lot of utility for setups, so having them fly all the way to the blastzones while retaining full damage and KB I think is a bit much. I can't think of a single other character that has an uncharged attack that doesn't peter off in some way, so I would suggest either nerfing it's range, or power throughout the duration of the attack, or even both. Whatever works.
Finally, I think his weakened ledge attack still needs work. It lasts longer than any other move of that type in the game, has the most range, and then he's still invulnerable after he climbs up on the stage when it's over. I love the animation though, but I feel it would be better if instead of doing 3 long stabs, make it two quick stabs WHILE he climbs onto the stages. This would put it more in line with the other attacks.
That's just my two cents for now. I know some of these suggestions may go against your design ideals, but I'm of the opinion that for fan projects like these, it's better for a character to be slightly underpowered than for them to be a broken unstoppable monster. If it's underpowered, it just takes that much more skill, love and devotion to make it work. Then, the satisfaction that comes after winning is priceless.
If it's OP, then even if the character's fun to play, the satisfaction you get after victory feels cheap. As it stands, I don't even like playing against other humans with Ridley because I don't feel like it's fair fight, and that's
an issue that's even bigger than Ridley a huge problem.
