Our note
Gameplay from a text-glyph deep-sea horror game where a small submarine glides through glowing ASCII cave walls past lurking creatures as the depth counter climbs, made by Claude Opus 5.5 inside the author's own engine with no other prompt.
The creator’s post
I asked opus 5.5 to make a game within the confines and abilities of my engine, no other prompt. It made this deep-sea horror game, with a subtle drone soundtrack. And it's terrifying (if a bit unbalanced/unfair). Sound on.
