Honestly I'm not understanding the negativity toward MM5GRA. Usually in servers I see a lot of people enjoying themselves on the map (especially CTLMS servers oh god the strats are fucking insane). The gimmick isn't as restrictive or boring as MM2QUI, overbearing like MM4DIV, or over-implemented like every rendition of MM5WAV. You see me talking all sorts of shit about
bad map design, well MM5GRA is pretty damn good if you ask me. There are almost no spots where you're TRAPPED, the gravity mechanic is easy to predict and play around, and you're allowed a lot of room to put those juke shoes to work.
If you're really having trouble with the map, I'd suggest thinking about hallways you could cut out in areas like
here. It's an area very few people think about despite its usefulness, so drawing attention to it would alleviate a lot of navigation stress.
I'd also like to see if
this little alcove being turned into a shortcut to
here looks any good. You could probably turn that little alcove into a room as well (yeah i know look at me wanting to make a map BIGGER).
Whatever you propose/change, though, keep in mind the whole point of MM5GRA: Path changing and adaptability. If you end up homogenizing the map and making all paths accessible in both gravity states, you defeat the strategic purpose of the map. Honestly, you haven't fully experienced this game until you've seen a good round of CTLMS on MM5GRA. Small skirmishes all over the place, creative movements, baits, outplays, escapes, a whole fuckton of awesome shit happens on this map. It's comparable to MM5DAR honestly (which is the best map btw).
Wasn't there a Rockman no Constancy mod that had a map with inverted gravity or something? If it were possible to implement that, it would be great. Else, well... How about consider a larger fighting area for high gravity, with blocks and props for the player to hide behind'em and maybe one 3D Platform Elevator?
I would consider a true gravity flipping mechanic to be wayyyy too intrusive (even thought what we're talking about is just walking on the ceiling like cbm gravityman). Blocks and props sound pretty good though. I wouldn't mind seeing a couple of those in the big Pharaoh Shot area with GHold, possibly leading up to the teleporter. Maybe make the tele a 2-way?
