Code-as-mechanic puzzles
Puzzles are actual code constructs: null dereferences, off-by-one errors, dangling pointers. Solving them means understanding them — no pattern-matching, real comprehension.
Think like a compiler
Puzzles built from real code constructs — null pointers, off-by-one errors.
Choices that persist
Variable rewrites affect the story chapters later — the narrative remembers.
Branching narrative
Your variable choices persist across chapters. Rewrite the wrong value and a door closes three acts later. The story remembers everything you changed.
Unlockable debug modes
Complete chapters to unlock debug tools: memory viewer, stack trace inspector, breakpoint mode. Use them to go deeper into the game's own source — the meta-layer is part of the story.
The game has a debugger
Unlockable debug tools let you inspect the game's own memory as part of the story.
Built for speedrunners
Category splits, in-game timers, and direct leaderboard submission.
