RKGGKeeper

RKGGKeeper is a portrait-mode casual survival mobile game centered around a moving safe zone. Players drag the character with their finger, closely following a constantly shifting and resizing diamond-shaped area, trying to stay inside it as much as possible. Staying in the zone continuously earns points, while leaving it and exceeding the time limit results in immediate failure. The safe zone keeps moving, with the pace gradually accelerating, testing reaction and anticipation. The main menu offers direct start or help viewing; during a match, you can pause at any time, with options to continue, restart, or return to the main menu. The end screen shows the current score and the highest score. Simple controls and a tight pace make it suitable for short sessions to challenge higher waves and higher scores.
