Manga which is completed and has reasonable length - not too short, not too long.
It brings what is promise, isekai, game mechanics in world, interesting world conflict, good explanation of main heroins powers and role. So full satisfection on this part.
Main weakness for me is that it should have ended in two thirds, where main arc is practically finished. At that moment is pretty obvious haw last third will end and there are no true challenges in followup story. It is more like season 2 in this part.
But still, I am happy I rad it.
