As you progress, enemies will start to move slightly faster and appear in more varied formations. You'll encounter enemies that require multiple hits to destroy, indicated by their changing color or visual state. Prioritize these larger targets, but don't neglect the smaller ones that can quickly overwhelm you. This phase also introduces the first 'Overdrive' power-ups, which appear as glowing red cubes. Collect these to replenish your Overdrive stock. Remember, Overdrive clears all on-screen enemies and grants temporary invincibility, making it a valuable tool for tight situations or for clearing out a large number of high-HP enemies quickly.
