I’ve never played any Fire Emblem games so maybe some of the things that should be obvious to your target audience just aren’t to me.
When using the “attack” action, it took me a bit to figure out how – or that I even could – select which unit I’m attacking. The selection window just looks like a confirmation window, and I didn’t see an obvious indication that I could scroll to select other enemies in range.
I found myself losing lots of units. I know that I suck, but it also feels like it’s unavoidable. Are units meant to be somewhat disposable? If that’s the case, giving them all names and portraits seems cruel.
I like your visual design. Colorful and comfy.
