Roper is definitely a trash tier character. It seems the best way to play him is to throw dynamite and run away when crowded. The slight hesitation in his punch combo leaves him open for other attackers to pounce, his I-frame bowing attack is slow, pressing the wrong button at the wrong time can lead to him moving out of position (he has back and forward movement assigned to attack combos), and the physics for his jump tend to do weird things in the platforming sections. Bleh.
