Oh, how i love the Sounds and the music, its so calming! And its fun to play too! I love the idea, it reminds me of the grappling hooks in Terraria^^ Unfortunately i miss the "joined together" theme a little. I get the idea of "attaching" to the level but i think "joining together" also means a focus on the "together" and in your game it doesnt seem like there is a "together" because there is just sort of one "dynamic actor".
But nevertheless, i really enjoyed playing this! Great Submission!
