2/5 too bad gameplay, did it only for badge. 10min survival mode took more than 12min. I did half of lvl12 survival mode without shooting only sliding around the arena. i'm sorry, too bad
2/5 very unbalanced,
bad gameplay: if you learn how to predict and bounce shots, your game success depends only on radomness of units entering arena, their types and timing when they start shooting. many game situations are thus impossible.
