Consider adding a "cargo bay": an "inventory" that you can pick up/drop one item with. This opens up mini-games involving moving items about rather than just finding the appropriate item or destroying the right enemy.
Before the cargo bay is added, we need to think about what kinds of items would be Holdable, and what you would do with those items. Things one might do:
drop a holdable onto a stationary target to achieve a goal.
bring two holdables together so they interact to form a desired object (possibly another holdable, which could participate in other interactions).
make force fields that block the player, and have holdable field dissipators that allow the player to enter compatible force fields
in general, have holdables that grant special abilities only long as they are held; there may be several desirable (but mutually exclusive) holdables.
Movement powers are added.
