5rtDagger is a vertical casual touch mobile game where the main gameplay involves swiping your finger within a time limit to wipe dust and dirt off crystal discs set in hexagonal golden frames. You score each time you complete a clean, and as your score increases the discs shrink, the dirt thickens, and wiping becomes harder, gradually raising the difficulty. If you fail to clean a disc within 3 seconds, it counts as a mistake, and three mistakes end the game. The game supports pausing, restarting, high score tracking, and switching to the main menu. It's easy to pick up, fast-paced, testing both reaction speed and your sustained focus and strategy planning.
