Space Invaders Type of Deal

Hey, G-Develop! It’s been a while.
I’m looking to make a new game, similar to Space Invaders, on mobile, where you slide your character left and right to avoid oncoming asteroids. Two questions;

  1. what game format/physics should I use to develop this type of game?
  2. what should I do to allow the player to slide the character back and forth?

for movement left and right you could use buttons on screen, like a keypad.
To your first question I don’t know, for my game I created an arcade but then I do most things like not leaving screen. Maybe it can be done by gdevelop for me :confused:
