You've got a nice tileset and character sprites! I recommend setting your Unity project up specifically for pixel art to prevent sprites from resizing as you move around and gaps from appearing between the tiles, this change alone will significantly improve the look and polish of everything you've made so far. I didn't find anything to do outside of exploring the area around the house. I hope you'll keep working on this game, you'll have a lot of fun making new additions now that all of the fundamental game elements are in place!
