How does your submission match the theme?
Almost everything in the game is designed to work in multiple ways. Some examples:

- Shooting bullets slows you down, giving you more control over movement.

- Shooting is used to both deal damage and to push bombs around the play field.

- Powerups can either be used as weapon modifiers or as bombs.

- Bombs clear bullets that they hit from the play field.

- The fire powerup is short-ranged but deals more damage.

- The lightning powerup is short-ranged and can hit through pillars, but you cannot detonate bombs.

- The metal powerup knocks you back and can knock you over impassable terrain.

- The lightning bomb attack has a larger splash radius but deals low damage and paralyzes enemies it hits.

- The metal bomb attack destroys pillars that it hits, eliminating the player's cover but giving them a health pack.

- Players score points for extra time but also for damaging enemies and clearing bullets with bombs.
