A really good feature (I think) would be to select groups of buildings or items for your companions (or genies) to work on offline, instead of just one.
Great game! You asked for comments and suggestions, so here they come. Thinking about the character that is played, set in a village that seemingly doesn't have any other defenses, they are forced to rely on the dungeoneer for help. If that is the case, it doesn't make sense that the quality of equipment continues to get better with each successive round. There should be a cap on quality that a small village can provide from sheer lack of resources.
A higher reputation, as noted by the dungeoneer's name becoming a profane term when they get high enough, should also attract the attention of other villages and cities on a world map. This could give players the ability to travel the game world to break the monotony of only slaying dragons as the main climax in the dungeon. Perhaps a demonic portal has opened up and threatens another city. Maybe a thieves guild network hampers the dungeoneer in some way for its own gains, etc.
Suggestion to Dev: You need to make this available for Android in the play store. This is the only IDLE game that has continued to hold my interest... Well done! If you do make it available for Android, please don't be privacy invasive like so many other apps are. You might find ways to have in game purchases without it impeding progression, to further your development. There is a great chance of being highly successful... at least I think so. I was thinking to expand the game through the role of the hero by unlocking new knowledge skills. As he/she explores new territories through their interaction with new cultures, like an emissary learning something not native to their own homeland and sharing it when they return. This could be a spring board for other future development and bringing life into the game through specialized characters.
