Marnel Fold is a reaction and speed based game. Panels light up on the field and must be tapped while they are active. The longer the streak of correct taps, the higher the score grows.
Level 1 uses a 3x3 grid. The session lasts 30 seconds and only one panel is active at a time. A correct tap increases the score and builds a combo streak. An incorrect tap reduces the score and resets the combo. The speed gradually increases during the session.
Level 2 expands the field to a 4x4 grid and lasts 30 seconds. Two panels can be active simultaneously. Score from Level 1 carries over and combines with Level 2 results. A score multiplier is applied during this stage.
At the end of the session, results are shown in a local scoreboard. The game focuses on timing, concentration, and rhythm in a clean minimal interface.
