Must say that this is really bad, especially Storyn. I ended up playing the game on late nights and managed to play it last night.
Highly recommend the game and especially if you play any of the other Fire Emblem games. The game is somewhat harder than the previous Four Emblem games as it places greater emphasis on strategy.
There is a greater difference between different devices. An archer who made a class change can shoot 5 squares and thus, for example, shoot people outside their danger area.
Sometimes the ground is malicious, which means that strong flying units can be very worthwhile on such lanes. If you are weaker than the enemy, it may also be worth fighting inside a forest for better protection from the terrain.
Played the game in Normal mode which is generally a good way to experience the Fire Emblem games because you can actually make some mistakes and so on.
But this game has actually made me want to run a second play through on classic mode where devices actually die for good. First, you have a magic that allows you to turn back the time in the game. There also seems to be a way to revive selected devices, so that as long as you glue a bit and keep the devices strong overall, you should be able to get through the game as well (like a kind of hard mode).
