In Broken Knuckles, Knuckles will die if you will try to press Left or Right on the controller while he is standing, running, rolling, gliding or jumping.
You can use Left or Right only to beat the special stages and to interract with objects (climbing and hanging on poles, etc.), except for pushing them.
To beat the game you need to utilize Knuckles' abilities to glide, climb up and down, spin-dashing, and his momentum.
