I would've given the game a good rating but seeing how I racked up over 100 kills from lvl 25, I didn't...... The timing on the bottom of the map is making it literally impossible to get past..
Wow night before the game gets its achievements i complete it with all gold etc. Log on few days later and end up not having the achieve for the all gold... Had to do every level with the black hole or w/e it is vial... man that thing is fun bahaha
