Modified 31 October 2026 for TFA Games. Original creator attribution and applicable licence notices retained. Files inlined for opaque-origin sandbox playback, network connections disabled, progress stored only in memory. No TFA authentication, analytics, advertising, purchases or competitive score integration.
Author-supplied build adapted. Payment meta pointer, manifest reference and service-worker registration disabled. Removed the compiled build's unconditional paid flag; the original free puzzle sequence ends with the original thank-you screen instead of a payment prompt. Animation delta capped to prevent off-screen drift after inactive tabs. Original title vector recoloured and framed for the catalogue cover.
