may i suggest some epic stuff for a possible "better than melee" version?
ok, first of all the 3 day system, all the brawl stages work on a 3 minutes loop, so you could make every minute a day xD or 3 minutes a day, idk...
second, extra effects for third day:
small gravellish stones, i'll elaborate a bit...:
on the third day (specially the night), the moon is VERY close to earth, so some gravity weirdness could be expected, im not asking for a gameplay gravity change, just have some random stones (4 or 5 vertice items, and very small) all riged to one or maybe 2 bones, they should kinda levitate and shake a lot...
camera shake, since the moon is so close, the earth should be shaking, best way to fake this is by shaking the camera a bit, idk how this is done, but i assume it's possible, if not, just shake the whole stage model xDD
if you end up making this "better" version, i'll come up with more ideas to give it this epic appocalypse feel
