Miracle Brave: Beast Defense Line

Wants to be Zero Stress King. It plays almost identical with less mechanics. As you play the game it is wave based. Blue crystals is the only currency at the start. Which appears at a snails pace. Each time you fight a boss it doubles the resources you get. But also increases the health of all the creatures you face. In the end your goal is to reach 5-4. Which right now is merely just a slog waiting for resources to max out. Since your goal is to finish the skill tree entirely. Every character you unlock adds a synergy with another. But there is zero actual choices that matter other than increasing damage all the time. There is no prestige mode or anything. Just mindless going from screen to screen.
