managed to make it up to the top left area but got stuck there last night... will keep on trying

is there a hotkey to pop all your bubbles?
you can jump into a spike and respawn to get your bubbles back if it helps!
hmmm i cant get past the first key on the right...... feels like im missing a hot mechanic
this took me a long time to work out,
a popped bubble will launch any bubbles next to it, you can use this to place bubbles in places you might not otherwise be able to reach e.g to make a three-step staircase
