This is a pretty fun game that's this close to being very fun (and addicting) game. This basically feels like one of those mobile game ads you see for endless runners, but then actually fun. The combination of moving between lanes and aiming at and shooting targets has great potential.
The main issue right now is that the controls just aren't quite satisfying; and for about movement, this is of course something essential. For me, this mostly stems from the fact that you teleport rather than gradually move when pressing A/D, and that the over-the-shoulder camera while shooting can be a bit janky / that your missiles are often blocked by trees etc., sometimes you too little time to actually hit the targets. I think just a bit more polish to these aspects can go a very long way for this game, and I'd be interested to see where it would take it.
Also, to be completely honest, this game doesn't really feel related to 'Flow', and the explanation feels like a bit of a stretch tbh. That being said, this doesn't stop the game on its own from having great potential.
