Treat a light-signal round and a tug-of-war round as separate tasks.
The listing names two activities
Sprunki Squid Gaming describes a sequence involving Green Light, Red Light followed by tug-of-war with a friend. That establishes a change of task, not a shared control scheme. Before beginning either activity, read the instruction for the current round. A successful movement habit from the first activity may have no relevance to the timing or input expected by the second.
Use the visible signal
In the light-signal activity, establish which on-screen cue actually indicates the permitted action and which indicates stopping. Observe how your input maps to that cue rather than assuming that color wording alone explains every rule. This is an interface-reading question, not a tested timing trick or a guarantee that an animation provides a safe reaction window.
Reset the plan for the next round
When the game changes to tug-of-war, pause to identify the new objective, available input and feedback. If playing with another person is actually supported in the supplied build, agree on the displayed controls rather than competing with different assumptions. The excerpt is truncated and the controls only say mouse or touch. This note cannot confirm local versus online multiplayer, the full sequence of rounds or content suitability. Read the actual presentation before continuing, especially if the fictional elimination premise is not the experience you want.
