Couldn't get any farther than the second level, which I think comes down to a few things. Since the enemies can move just as fast as you can, it's very hard to get any distance away from them, making it certain they'll shoot you from point-blank range if you press shoot. This led to me running around a lot, trying and failing to get the enemies off my tail. Even if you've got them aligned well, they take a lot of damage and therefore take too long to kill for my liking.
The control scheme was a bit hard to understand at first, and even after getting used to it, it feels convoluted with moves that feel unnecessary. Like, why does there need to be a strafe toggle if you're not the one shooting? Why does there need to be camera control when the top-down perspective works fine as is? What do the hand attacks to the conceit of the game? (Actually, that could maybe be useful if they helped to get the enemies off your back.) What does jumping add? Maybe these things see more use in later levels, but the first level didn't convince me.
There's also some performance hiccups when the stage loads for the first time, and the audio was a bit weird. I appreciate that you added both music and sound effects, but they sound a little out-of-place in a way that's hard to explain. Overall, I can see what you were going for, but it ought to be more approachable.
