I hate to be a downer, but the game is WAAAY laggy for me after installing the update (and restarting my iPhone). I used to be able to quickly get x3 and x4 combos by being quick with the blocks, but now it's too laggy for me to get anything over x2. These issues are happening with normal blocks, not with the special ones (with the cool graphics that could slow something down).
Mine actually worked fine until my 4th level up or so. Then, it became so laggy that it was unusable. I tried restarting the app, but it didn't help. I'm rebooting my iPhone now in the hopes that it will fix it.
