the blackboxes or sprites not showing are caused by your browser not being able to load the game (the game is 340MB which is quite large). If switching browser doesn’t work then you will have to use the downloadable version for now.
Look, i used the downloadable version, it didn't work, i responded you and went for the browser version, got the blackboxes, reloaded the page and could play normally, do you think it might work if download the archive again or reset it? it's the only thing i didn't try yet. Also: Thanks for answering my questions so quickly, sorry for being slow, i just post things and close the site where i posted the thing.
no prob, what happens when you try the downloadable version? if you must use the browser, see if this version works for you: https://fierylion.itch.io/a-bellyful-life-small-res
