Love the style of these! Are you still planning on doing outlined versions? As they are, they're not really usable, because when you select them in combat, it highlights the pixels of the targetted enemy, so it either highlights a box, or the enemy minus its transparency.
Yeah, I got all three packs and noticed that one set had outlines. I'm surprised you hide the flashing targets, because even an enemy's death animation alters the pixels so it fades out with colouration. I guess you could just make it fade out with increasing transparency instead? Thanks for awesome monster packs, either way!
