I always move towards the tiny circle things thinking they're bits, and then die. Honestly, that was kind of a d1ck move to make the collectibles the exact same design as the enemies.
Found a glitch that makes you replay the final boss. AGAIN.
If you rush into the zone where the final boss is, he is invisible, and no health bars or meteors are present. You just jump around on the fishes until you win. No cutscene, either.
