In this game, four pictograms are displayed (represented by emojis in the provided code). Each pictogram will flash in a sequence, and the player needs to repeat the sequence correctly by clicking on the pictograms in the same order. As the player progresses, the level increases, and the sequence becomes longer. If the player makes a mistake, the game will end, and they can start again.
