What a fun premise, running an Adventurer Evaluation Center and testing people with hologram monsters! I liked that the tutorial does the math with you (a 25 HP swordsman vs one 5 dps slime should end at 5 HP), and the yellow 50% marker on the health bar makes the goal instantly readable. Choosing monsters by HP, DPS and rank, then thinking about spawning one close and one far, turns each evaluation into a neat little puzzle. Clean pixel art and a really clear UI too, great job!
