This game is super polished, and I like the way it introduces new mechanics. It is pretty funny being able to throw your brother around. :3 The gameplay was really smooth, and it was nice that I was always able to easily pull the brother back with the rope (even if it didn't conform to physics laws xD).
One critique (may just be bc I'm pretty bad at these types of games) is that I often felt like I had no idea what my goal was, and would just wander around the map hoping to find something.
