I enjoyed the different mechanics implemented here like the army recruitment system and battling on the world map vs the solo unit exploration of dungeons but some more explanation is needed to the player conveying the differences between the two and what is going on.
I am somewhat perplexed by the lack of audio in the game. Sometimes no audio can be utilized effectively to create atmosphere in a horror game or small sections of RPGs to build tension but there is literally no background audio in field maps, battles, cutscenes or anything. You don't have to go buck wild on this but including some basic audio in certain areas would definitely help the player enjoy the game experience more.
I think there is some good potential here as you have implemented some creative ideas. Thanks for making the game and sharing!
