Additive for a few minutes.
Concept is great, The gameplay is smooth. Very easy controls. Tends to get very repetitive, I would of liked to see more power ups, more weapons to choose from, more enemys. Different difficult levels to choose from. It would of made this game unique if maybe you can edit your flying birds features. Very fun game, had me playing for 20 minutes until it got very dull, it lacked features to keep me grasped. Not a bad game, i would like to see this evolve to something epic.
