I just figured out the score bug. Does anyone else know about this?. When you submit a score it takes your best time and your best score
separately. I played it once as fast a possible to the get the 16:00 (ish) (It was still a little tedious). And then replayed it to get the score gems which took me about 35:00. So the scoreboard took my 16:00 time and my 26,000 score from different games.
I guess why I commented is that this map is
sooooo close to being great. I played it like 5 times (I rarely replay maps) to see if there was something I was missing, like surviving the 2:54 phantom assault with ANY crystals left. I want to modify this map and resubmit it but it's not my map.

seperate time and score is known, doubt it was a bug.
most authors will be ok with the map being tweeked by another, as long as you make it clear in the map description and info box that it is a reworked map, i think that this is ok from knucklecrackers point of view.
if not just be inspired to make a better map with the bits you like in it.
