I have recently downloaded peggle 2 on the ps4 and so far it has been quite enjoyable. However, after unlocking berg the game has no longer been a challenge. Every level has becone a joke to clear and net 500,000 + points. I honestly believe that berg's super freeze ability needs a nerd as the game is no longer enjoyable with berg unlocked.

TL;DR Berg is overpowered and needs a nerf.
