This was beautiful! As someone who is starting to get into pixel art now, this was very inspiring to see. You created an awesome little world :) I loved some moments like when the kid is dragging himself across the fort, or the animations/sounds of the sibling falling from the chair and the plushies also falling from the chair...
the gameplay is simple yet challenging, allowing the player to just really immerse in the world and enjoy the moment. Overall an amazing entry, great job!
