I'd still consider the free games in the Playstore with the similar gameplay

The game is nothing that special to the ones that are free.

I am not a total fan of the animation of the enemy flyers that are in the game.

It could probably use a better design of it.

I would think that the graphics of it would be the selling point of this game, so probably if there was an update, there would be better-looking enemies. Still not worth my purchase.
