I have not tried it yet but i saw my brother play it and i read the comments and the inventory sounds like a big issue. When pets die you should be able to resurrect them some how. Make hot keys, bigger inventory or ,like in pokemon, different pockets for different types of items. Giving the pets equips that increase they're attack would be nice.
to louis lui and all the other ppl who want the hosptal ending all u have 2 do is stay home and then klik the response at the top for the rest of the game thats how i did it
+1 if this helped
