The concept is pretty cool, and you have to add ways to earn points and keep. The game is quite difficult, keep it up.

it's simple but fun. i would add, a warning, a mark from were i

I  can't really  count move to the left and right as to  actions, it's a toggle, itself the limitation open to 2 big ways to interpret it or you can make thwe button do diferent thing in fuction of if  you kick  press, press in succession, or hold each making a action,  of press the button do .  See this one of the jam https://itch.io/jam/mini-jam-162-heat/rate/2819089, it's mechanically similar game(but inverse it move automatically an you  can invert direction and stop it). Mine use same interpretation in a diferent way.
the other interpretation is to make 2 thing ad the same time like jump and .shot
