Hello
the graphics look unusual, a bit outdated for me, which is not meant in a negative way. difficult to assess what the developer and story wants to build up, especially since the few tags hardly give any information about what could/should happen in the sequel.
if you are a developer and want to have as large a fan base as possible and want international attention, you should consistently use the english language for development. if you start this game in english, you will always come across portuguese ingame for writings / instructions in the graphics, on the map, in the menu and so on. if you do not speak / understand portuguese, you will inevitably have to resort to manual translations if the information does not make any sense.
For me personally, this is a reason to avoid such games/VNs unless they can also clearly distinguish themselves from similar projects. the selection is just too big for that.
it remains to be seen whether there will be a fully english version in the further course of development.
I wish the developers good luck.
