Attack The Light

Save single-use buffs and debuff items for Bosses.

You can get an extra hit if a gem is tapped as soon as it appears.

Use the correct skills for the task. If needed, end a turn while you have star points remaining. They may be more useful when used with the points you are rewarded at the start of the next turn. Garnet's Shield Breaker skill will weaken powerful enemies. Steven's Encouragement skill is useful; upgrade it early in the game.

Star Fruits are common. Use them to make things easier.

Although you cannot block each enemy attack, you can do this to many of them. Either tap the screen once or repeatedly.
