I'm thoroughly enjoying Idle Underworld, the auto-battle system is so satisfying! I love that I can upgrade my units with the unlimited money feature. My only suggestion would be to add more UI customization options, though.

Unfortunately, the app freezes occasionally, especially when I'm upgrading my units. Maybe it's a modding issue, but it's still frustrating.

The user interface is a bit cluttered for my taste, but the layout is at least consistent across the app. I'd appreciate a cleaner design, though.

The unlimited runes feature is a lifesaver, I can finally progress through the game without worrying about resource scarcity. Great job, developers, keep up the good work!

The modded version feels really unfair compared to the regular game. It'd be great if the developers balanced the resources or released a competitive multiplayer mode.
