Ah, I see. Thank you for the explanations! I'll keep them in mind for future projects.
Just to leave it here for anyone interested:
- Win/Draw/Lose: If one side has no units left, the other side wins. Otherwise, if there are no more possible moves, it's a draw. The number of units left for each side determines the damage dealt in that round (with a multiplier depending on the difficulty). Win grants a bonus shopround to the winner and does not otherwise affect the damage.
- The timer represents the "Turn Delay" (couldn't come up with a better name). It determines when the unit is allowed to act, with smaller being better.
- The purple square is indeed related to the link effect. However, all link effects (positive and negative) always affect the enemy only. On lower difficulties, you have a higher chance to debuff the enemy unit, while on greater difficulties, the buffs for the enemy become stronger.
