The "Little Gray Cells" minigame challenges players to logically connect pieces of evidence, such as witness statements and crime scene details, to deduce the killer's identity. This requires careful attention to the information gathered and critical thinking to piece together the puzzle.

The adaptive dialogue system allows players to tailor their conversation style with suspects, choosing from various options that can elicit different responses. This encourages players to observe each character's behaviors and personality to determine the most effective approach.

The timeline feature helps players keep track of the progression of the murders, enabling them to visually map out the sequence of events and identify any inconsistencies or connections between the cases.

The game faithfully adapts the classic Agatha Christie novel, providing players with the opportunity to experience the iconic detective Hercule Poirot's pursuit of the elusive "ABC" killer. The cat-and-mouse dynamic between Poirot and the murderer keeps players engaged and invested in unraveling the mystery.

The engaging mystery challenges players to think critically and uncover the killer's motives and identity, offering a satisfying sense of accomplishment when they are able to accurately reconstruct the events of each murder based on the clues gathered.

The high-quality voice acting, particularly for the character of Hercule Poirot, brings the story and its cast to life, immersing players in the period setting and atmosphere of the game.
