Symptoms of Open Hexagon
The main symptoms of Open Hexagon are:

Hallucinations – where a person hears, sees and, in some cases, feels, smells or tastes hexagons that do not exist outside their mind but can feel very real to the person affected by them; a common hallucination is seeing spinning hexagons around.

Delusions – where a person has strong beliefs that are not shared by others; a common delusion is someone believing there's a hexagon to harm them.

The combination of hallucinations and delusional thinking can cause severe distress and a change in behaviour. The person usually thinks that he/she's a moving triangle trying to dodge hexagons.

Rumor has it that if the person fails, the hexagon gods will wake up from their sleep and drag the universe into an apocalypse. Please do not play this game for your own sanity and safety.
