Cool update! I really like the new ability to spawn multiple balloons. The feature the last comment suggested to let you reinsert the hose to keep inflating them after would be nice. Since air visually passes through the hose now, I also suggest adding the ability to pinch it closed so you can let it build up and rush in all at once.
The only issue I've noticed is with the dragon balloon: in game, its tail, horns, and back spikes render inside out, and its icon is missing a nostril.
