I read the manga like five days before I found it was already adapted into anime, a bit shocked and confused about the art, like, is that a reason to make it like that? until I realized, in manga version, when the MC isekai'd into that forest in eps.1, he said "At least organize them into HDD first..." I think that's refer to the game's graphics quality, so I think that's why they make the art like that, besides the animation budget. Well, I enjoyed watching the anime as well as I enjoyed the manga. Hope this will get season 2.
