Bugs found in Dungero: Rumble Offline RPG for iOS
Dungero: Rumble Offline RPG is an engaging tunnel-style role-playing game that challenges players with intricate dungeons, monster battles, and strategic decision-making. It features multiple difficulty levels, diverse skill sets, and a variety of customization options suited for both casual players and hardcore RPG fans.
Despite its overall stability and widespread positive reviews, Dungero occasionally falters in meeting modern performance expectations. Notably, a 120 FPS setting—crucial for higher-end devices—remains absent, possibly limiting the game’s visual fluidity on some newer devices.
Our QAwerk team conducted a detailed Bug Crawl of Dungero for iOS to identify any critical or performance-related issues. Below is a summary of the key findings that may diminish the user experience and smooth gameplay.

During the Bug Crawl, I observed that Dungero: Rumble Offline RPG remains robust under normal use but reveals a few flaws, including the ability to bypass tutorials by dying, the absence of confirmations in critical sections, and minor UI inconsistencies. Addressing these issues, alongside implementing high-performance settings (e.g., 120 FPS mode), will greatly enhance the gaming experience and align Dungero with modern RPG standards.
