I freely confess that I feel pretty terrible at this game; certainly I'm way worse at it than I was at FTL. As of right now I haven't managed to make it through two fights before losing all my powered buildings, let alone complete the first island, and that's on Easy mode. I know Chris Avellone had some tips on Twitter yesterday (not in a reply chain, so you'll have to go to his Twitter page to see the rest):
Into the Breach Tip 1: While your human/robot pilots can get replaced with A.I. units when you die, try to keep them alive - the fact they gain experience points and Mech unlocks can give you an edge A.I. units can't.— Chris Avellone (@ChrisAvellone) February 27, 2018
Anyone else have any tips or tricks to share? At the moment I find the difficulty more punitive than fun, but I'll keep banging away at it until I get frustrated enough to quit, I guess.
