As another reviewer mentioned, the game is very much like URIDIUM for the good ol’ C64. Except... and here’s the bad news... both the graphics AND the controls are far WORSE than they were 30 years ago. COME ON! What’s WRONG with you people? Things are supposed to get BETTER. You know, advance, improve, develop? Geez..
On-screen joysticks are usually terrible, but in this case the on-screen joystick is such a slow-response PIG to use that unless you have a controller I wouldn’t bother.

It’s like the iOS version of the classic Urdium. No surprise there as the guy (Rob Hewson) behind it is the son of Hewson Consultants Andrew Hewson back in the 80s.

Great graphics. Controls work very well. A nice shooter different from the usual you might see on iOS

Well worth picking up. Indie heaven

I backed this game on Kickstarter. Why? I loved Uridium on the Commodore 64, and the idea of a modern shoot em up based on that game was what I wanted. I wasn’t disappointed when it came out 😀... great game play, fantastic graphics and gameplay.
