I do not really see why I should play this over Skyforce, but I could see this being interesting for people that already finished that one. I feel it is not on the same quality level of Skyforce though: The controls are responsive, but the hitbox is somewhat weird. The weapons, effects and sounds miss the immersivness of other games and the quality of skyforce .e.g they feel bland. On top of that the IAP, Energy and currency stuff. Even though i do not know how much this game will get gated by it, I know that I can play a while day of Skyforce (multiple hours in one sitting) without needing to purchase lives or even the speed up IAP. Anyways. I feel like there are more quality made alternatives out there than this one, but if you already played them I would give this game a go regardless of all the comments in this thread, it seems ok base on my first impressions.
