Really great retro arcade vibe! And who doesn't love shooting stuff in VR :-) Overall it seemed very polished. Well done!
However, I kept having a problem with the gun being stuck facing a weird direction. The first two times I launched the game it was facing backwards, and I couldn't shoot anything. On my third try, it was just kind pointing maybe 20 degrees to the left, and I was able to successfully play. (I was on a Quest 3 using Steam Link)
