i had a wonderful time at Genesis. So far it looks like that if you're good at melee, you're good at project Melee, too.
Now for some discussion, I guess!
I played AT LEAST an hour of friendlies with KOF, maybe even more! Falco/Fox vs Zamus, and I noticed that she has practically zero escape options. Falco can just control her space, and crouch cancel all of her fast normals. Once he's in on her all he has to do is push buttons. I personally elected to spam laser grab and shine grab a lot. eventually I had the guy conditioned to do certain things, and I started just standing next to him and hitting him out of his OOS options rather than trying to force it.
I did learn that arguably her best option vs Falco is her dash grab, especially near the ledge. Her fthrow and bthrow are wonderful gimping tools, combined with her good edgeguarding tools. It takes her far too long to KO him via attacks, because you can fairly easily SDI out of her usmash set ups, or just control her to the point where she can't even do them.
Bowser's probably mid tier AT BEST. Despite the massive buffs, he's still just bowser. Outside of the first game I played vs Bad Guy, the only games I lost were literally because I kept shielding near the ledge and getting klaw gimped. In fact, Klaw was one of the only things that DID hit me when we were playing. The first game I just kinda ran around and lasered and stuff to get a hang of P:M after a few months of not playing, and to see what Bowser could to. From there, I figured out that Bowser is secretly a worse Marth. The secret to beating the guy is to attack between his. Many of Bowser's aerials and grounded normals are fast, and have huge hitboxes, but take a billion years to end. What Falco does is wait for Bowser to attack, then kick him. A lot. Edgeguarding is fairly simple. Just kick him. If he grabs the ledge, stay just within the edge of Bowser's ledge attack range so that you can react to it, or laser grab a normal get up. If he ledge jumps, just laser and react to what he does from there.
Zelda is the over-hyped character of the day. Many of the brawl players, and a few of the lower level melee players were going on about how broken she was. The fireballs have hurtboxes and small hitboxes, so most characters can just attack through them. As Falco I just naired through them, or depending on the spacing, I'd often just short hop through any gaps. As for Zelda's attacks, she isn't really fast enough to trade with Falco, or Fox so I found that once I got in on her space, that was it. Sure, she didn't die until like 160% on a regular basis, but I found that it was difficult for Zelda to really do anything about it. Again, just grab her a lot.
With Fox, she becomes even easier. Easy usmash kos, and his Bair beats out her entire moveset, plus he's fast as it gets.
