Is there an auto-combat feature in the game?

Auto-combat becomes available after completing the game’s tutorial. While in Auto-Combat, all your units will attack automatically. They’ll also activate their special attacks (Skill 1) as soon as their energy gauge is full, regardless of the type of target in front of them. You can toggle their Auto Skill button in the lower-right corner of the screen to disable the automatic activation of Skill 1 for all units or you can toggle them individually by ticking the buttons under their portraits.
