Ah yes. I remember this one. The underwater space cave stage music was the only thing making that awful experience of having to control an awkward, plodding two-headed mini star whale through a dark, unsettling maze of pipes and abandoned structures tolerable. A haunted underwater space mining cave littered with exotic gelatinous enemies that would constantly flail their tendrils about as projectiles covered what little space remained to clumsily maneuver this space mammal towards the exit tube. Thank you for the bittersweet memory, Bertn.
