She's unavoidable seemingly at random, tracking my vertical movement faster than I can ascend/descend. I've been eaten with no way to escape in the first 20 seconds of Light over a dozen times. The lowest I've gotten the timer is 1:03. Sometimes she goes for squid ability decoys, sometimes she ignores them and goes straight for me. I don't mind difficulty but atm there's no predictable pattern or room for maneuver. You can't even reliably use the squid ability because there's so many eels and spicy fish around that you are too big to avoid while also avoiding the shark/mines/toxic waste/getting bounced around by sponges. I've played the level probably 50+ times now and I don't see how anyone can beat it without insane luck.
Also, are bigger bellies actually working? i got over 100,000 points in cruise and was so big sharks had completely stopped spawning, but the mermaid's belly seems to cap out at the same size it always did in previous versions.
