Just played the first scenario and the first adventure level on standard.
Pretty easy, so I might bump up to hard if the next few levels don't prove any more challenging. Presentation is great though, musou devs must be big zelda fans. Adventure mode gave me a huge grin on my face when I saw the map.
As my first proper musou experience, the name of the game seems to be "firefighting". Link and the other super characters seem to be the only ones who can really fight, and the others won't move, so it's down to you to choose the "best place" to be, if you choose wrong the enemy could advance on another front and take over the base if you're napping. Didn't happen to me, but I'm guessing it can become tricky on harder difficulty/later levels.
I replayed the first stage until I completed it with 100% map control. I can already see this game is going to be hell for the collectionist in me lol.
having fun
