Got through it only by restarting and using 5 hammers on the keys to unlock the yellows. Lost all my spaceship boosters as well. Pretty mean. Also I’m annoyed that the rewards for completing challenges etc are nearly all timed boosters instead of actual boosters now. Makes it much harder to build up boosters to deal with…
I’m having the same problem on 15 September at 10.00 GMT in UK. Can’t get anything to work, including hammers. Can only quit and lose lives and spaceship boosters. Please correct ASAP.
