The endless mode is fun so far, I've only encountered the Dual Mine so far since I lost to a 3 Ultimine round.
Will get back to Endless soon hopefully, but for now, it would be really cool if I could flag spots twice so I could keep track of the Dual Mines easier. Or better yet, cycle through flags to keep note of which mines are which.
EDIT: Got to 28! Came down to a 50/50 and didn't manage my resources. Also a multiple Ultimine round, man those are tough since I can't use Disarms easily, maybe it was just my strategy of trying to clear out areas so I could deduce the Ultimine locations using the hazard range, not sure if I should have saved the 3x3 reveal to kill Ultimines with Recycling. I think I've kind of confirmed my previous suspicious about Ultimines so I deleted my questioning about it. Still would like the flag switching between mines or something, any note system in the game would be cool.
