Use A and D to move. W and S are to jump and land. Space to fire. Enemies spawn from the left or right of the screen and will move away from where they spawn until they are killed or reach the other side of the screen. Firing spawns a projectile. The projectile will kill the first enemy it touches. If you jump using W, you will move at a constant speed and be invincible until you press S. When landing (S) you will kill enemies under you, unless they are armored (purple). Good luck Hold up because if this is 1D then the jumping is more like phasing through enemies
