I really like the main rope mechanic! It opens up a lot of fun interactions and felt intuitive to use, especially when you get around to just chucking your brother around. The dialogue also adds some nice charm to the game with the character dynamics, and hints at a greater story too!
I think the controls feel a little wonky at first since it had a weird mix between mouse and keyboard controls, but it made a little more sense to use the mouse once you got to the throwing sections. Overall, very fun and would love to see a version with full art and everything!
