This is the most polished take on the theme I've seen in the game jam so far, when taken literally (i.e. as two items actually joined together). The platforming and rope physics were very well done. That said, where this game shines is in its level design, and ability to teach the player each new mechanic smoothly and organically. The game felt great to play, and fun throughout. Great job!
One criticism is that it was a little unclear at times whether you would need to reach the blue goal, the orange goal, or both in a level, and potentially a way to see more of the level (e.g. increased FOV on button press?) might go a long way in enabling the player to plan out their approach more effectively.
