I'm playing on Windows with a keyboard (arrow keys and space bar). When I played I was bouncing off the wall every time I tried to stay at an edge, so I had to spam the left or right arrow key while also firing to try and respawn enemies away from me.I found it to be very easy and way better than the car version. I'm on PC, do you play the android version?
I personally found the car version much easier, and the penguin-seal sledding version the easiest.
