Here are some new ideas for the game.
Like new music to have some variety:
-Music for the main house (day/night or one type).
-Music for outside the houses (day/night or one type).
-Music for the shop street (outside and inside).
Other ideas:
-More objects that the player can interact with in the world.
Like televisions and radios among others.
-Special items that can be used to throw to attract or distract enemies.
