The game is won by successfully visiting all marked tiles or failing when Deca gets caught.
The core mechanic in Deca vs Rooko 2 revolves around navigating the grid by moving in one of four directions. Deca's movement is limited to a turn-based system, where each step must be individually taken. Players must plan their movements in advance to avoid enemies, which can block the path or remove one turn from Deca's overall time limit. The layout of the grid and position of enemies affect the difficulty level of each attempt.
The game requires quick thinking and strategic planning to successfully reach all target tiles within the limited time frame. It can be played directly in the browser without the need for download or registration, making it accessible for a casual gaming experience.
