Well, for those struggling with the battling:
You can control the character position with the ctrl button on the right. You can also edit your deck in your base. Ranged enemies can hit any enemy, melee only front row (i think), so place your char in back row, unless you have a significant dmg advantage.
'agile' can evade dmg and 'fast' can attack immediately, so keep some agile drones in the front row if you can.
The number on the left is the atk, number on the right hp. I think enemies only counterattack if their atk surpasses your's, but it might just be anytime they survive the first blow, idk.
Also, only draw as many cards (button on the bottom right) as you can play in the turn directly afterwards, you waste resources otherwise.
It's not that hard, but having an easy start with progressively harder fights (harder in contrast, not necessarily like this) is a nice way of doing it.
