Run out of flame ammo, fall, die. I don't think that was part of the plan.
So I was looking at how Team 5 did things, since they are several frames ahead of the leading teams in this latest segment I die in. Yes, it does appear that throwing Flame Charges in an area that looks ideal for just straight dashing is indeed faster by a few frames. Probably because I'd otherwise have to wait until I land before I dash, and also that a ground dash requires a few frames of us holding still and lasts 40 frames, while there's plenty of time here to get a Flame Charge up and ready.
Item drops went up in importance here. I suppose someone should start searching for convenient items.
