I liked it! I thought the movement was just a sling mechanic with extra steps, harder for no reason. Carefully aiming detracted from the fun...
But then I realised - the player can sling in mid-air!
But it's dangerous to spam, because the jumping character changes and could jump right into danger! That's a fun mechanic interaction.
Now to prevent the player from just clicking to swap characters - that's a thing I realised makes it too easy.
