Completed the demo on Switch and was not impressed.
Game is a bit blurry, framerate is not great with drops, texture poping and some ugly textures, far away bakground quite ugly as well, day/night transition looks like it is still in debug state with the screen becoming part black and textures being replaced directly without transition...
Gameplay is basic, it lacks style. I played in hard and everything was extremely easy, even beat the first boss (normaly pretty difficult in original game) without taking a single hit.
Stuff to pick up every two steps as well, awful.
Won't be buying this, thanks for the demo. I would say, take Collection of Mana instead, or Langrisser which has just been released and is extremely well polished.
