--- Update #2 :
A bad bronchitis got me, couldn't work at all :/
But I did plan ahead a lot before this time so it shouldn't affect the core game that much, though I probably won't have time to perfectly add all the features I wanted.
It's not quite what I wanted but heh, time's running out and it works so I'll roll with it. I'm giving myself tomorrow and mayyyybe saturday to polish a bit that part but I think I'm just going to start building the world next. Adding enemies, items etc. Colors are still a bit wonky.
