Agree, once you figure out Rinn can heal for free, makes the game a fair bit easier. Do like the res cost changes and the extra crystal/credits to start. Another bug I've found, if you start a new game in the middle of a fight, the lower buttons don't appear afterwards, so you can't buy new squad members.
It lets you start a mission with your whole team dead. Looks like you're stuck even though clicking galaxy gambit brings up the menu (not clear its a button)
I really can't seem to make any crystal in the first few fight as well.
yikes, that sounds like a bug. I will fix today!
