Lylat's platforms are low enough that Mac can jump up to them reasonably (and I think he can usmash the side ones, not entirely sure). On Duck Hunt the tree is so incredibly high that Little Mac can't get up there with a double jump. He either has to grab the ledge and use a ledge jump (which makes his approach more telegraphed and hence riskier), use an up special (not viable), or kill ducks and use the dog platform (both silly and slow).I just wanna mention if Lylat forces people to play an aerial game like BPC stated earlier.
And then AA bringing up LM bad on Duck Hunt but good on Lylat.... It's actually the opposite cause Lylat will **** Mac over too since again, the stage conditions you to an aerial game and lol LM aerials, lol LM in the air.
Little Mac is a bad character on every stage since, yes, he can't viably jump at you, and I would always be looking to exploit that weakness when fighting against one. Low platforms just make him thrash around a little though; high platforms like on Duck Hunt actually enable some very silly clock running against Mac. My goal when fighting Mac on a stage with a high platform isn't really to hit him at all. If he does something unsafe I will take all the advantages he's willing to give me, but what I'm really looking to do once I establish a lead is just to run the clock and win by time over. That's not realistic on Lylat while it is on Duck Hunt. Mac's main motivation is to avoid being lamed out by the stage selection; finding something actually good or bad for him otherwise is a secondary concern.
I can't speak for BPC's views on the gameplay dynamics of Lylat, but I don't view it as a particularly aerial stage. The very low platforms are more useful for defense and trapping people than aerial movement, and while some characters may find the tilting obstructive to their ground game and want to jump, that can really work both ways and there are clever ways to take advantage of the tilting on all sides. I actually think it's pretty neutral on almost every front but it adds a lot of little nuance, and in that way, it usually rewards the more careful and contemplative player who is able to form a better strategy to take advantage of the situation. You could say it's stressful I suppose, but I certainly don't feel more stress on Lylat than I do on other stages since I know that I'm well enough practiced with my character's recovery that I'm not more likely to mess up here than elsewhere. Also, real talk, no one has ever lost a game on this stage they didn't deserve to lose because of being caught under the lip, and it is kinda a bad look on us as a competitive community to talk about that being related to ban criteria since that problem is completely solved by a simple hour in training mode...
