Ben 10 Cave Adventure

You control Ben Tennyson, moving him left and right through a dark cave system with the arrow keys. The main goal is to clear each horizontal level of the hostile creatures that populate it. You jump across platforms and use the spacebar to fire energy blasts, carefully timing your shots to avoid enemy projectiles. The pacing is methodical; you often have to wait for the right moment to attack or advance. It feels like a basic test of patience and aim, a quiet, focused kind of action.
