Oups, the camera got stuck and stopped following me in the skyscraper-type building right before the tunnel to the science challenge. I have no idea where I am...
Not bad. It's a cool trick that you have players use even the area outside the game in the game, but I don't think you should use it as much as you do. The music's good, but the backgrounds are a little distracting. I'm also really bad at understanding hints.
All in all, I wouldn't say it's a BAD game. But it's not a GREAT game. The ball physics are unpredictable and some of the levels have weird layouts that don't help the physics. These layouts also made me get stuck while trying to go into narrow passages to escape zombies. If you can fix these, the game will be better!
I think this game has an AWESOME concept and is well made EXCEPT for the controls. I felt that wall jumping was too clumsy and it made me lose several times... 3/5
FINALLY finished all the challenges! The last ball is so fun... I think this might be one of the first 5/5's I've ever given. But yeah, definitely hotkey Restart. I hope you make another!
