Hi!
So I have read some dicussion here because I'm having trouble with level 977 too.
But the odd thing is, when I had a glich on the level where some balls wouldn't show up, there was two blasts available on the blockers area that I think helped win that level but after the glich got fixed they disappear. So, I'm continuing to try and win he level...
Can you bring the blast back? I think it helps win the level. Personal sugestion
Thank you
Eva
