We have a lot and I really do mean a lot of shooters, all with their own unique quirks and styles. Radar Warfare is pretty basic and that's being quite kind. Sure, it has a unique radar-inspired style going for it, but other than that it's a pretty straightforward dodge and shoot mechanic that wears thin pretty quickly. It does mix it up a little with the boss fights, but even those are pretty basic. The first boss, for example, was just sat in the middle of the screen and just fired a lot more bullets and a lot faster than the basic enemies.
I was hoping later in the game that something would jump out at me, but there just wasn't anything to get excited about. The spawn system annoyed me quite a bit too. If I was stupid enough to die, it would often spawn me right next to a target that was spewing out bullets giving me near-zero chance at survival. There were times when I just started a level and an enemy instantly spawned next to me and killed me, it was incredibly aggravating. It became quite difficult due to this too, but it's a real false sense of difficulty because the spawn system is quite unpolished making it more difficult than I feel it should have been.
It also suffers from some full-screen issues on Linux. It's likely built with the version of Unity had that the well-known fullscreen issues, as the mouse has no input in fullscreen meaning you can't aim. So for now you can play it in windowed mode, which does make the mouse actually work.
If you're not after anything overly flashy it's probably good to kill a few minutes of boredom, but not much more than that. A good idea, nice simple visuals, cool music but just not massively fun. With just a bit more enemy variety and a less terrible spawn system, it could have been much better.
