TickClock rechnet Bildzeit in Takte um und holt nach einem Ruckler höchstens fünf Takte auf. GridMotion bewegt einen Körper über das Kachelraster und lässt ihn an Wänden entlanggleiten. Die Figur läuft fünf Felder pro Sekunde, außerhalb des Gleichschritts. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
