Infinite life.
The hero of Robert and Stephen Hewitt's ambitious action-packed platformer Last Legacy: Null Space was just minding their own business, defeating an unspeakable cosmic evil, when they suddenly found themselves sucked into another universe by a wormhole. And it couldn't be the Red Pepper Hummus Universe, or the Psych Was Never Cancelled Universe, oh no. It has to be the Everything From Ghosts and Crabs to Fire-Flinging Mages Wants to Turn You Into a Smear on the Ground Universe. To find a way home, you'll need to battle your way through hordes of nasties, unlock new powers and find beefy new equipment, and master a strange power that will let you alter the landscape around you. And I'm not just talking about the robust level editor either. See, pressing [shift] will activate your Delta Powers, which lets you place up to three blocks anywhere within range of the blue orbs, as well as remove up to three squares of natural terrain. Red orbs, however, will prevent any block manipulation around them, and figuring out how to work around them, or even just manipulate the blue orbs so you can get their sphere or influence where you want it, becomes the real challenge of the game.
The default controls are [WASD] for movement and [spacebar] to jump and double-jump, but happily if you open the options menu with [ESC], you'll find they're fully customiseable to whatever suits your needs. Your goal is to make it through each stage intact, collecting golden triangles along the way to spend on equipment and upgrades between levels, and doing so usually involves kicking, stabbing, or magick-ing your way through enemies in your path. Finding your way to the portal at the end of the level is usually easy... it's figuring out how to reach all the treasure that takes some work. If you die, you'll be sent back to your last respawn point, and it's not just enemies that can do you in... falling into the nothingness between land and platforms is an instant KO. The game's downside, however, is that movement just doesn't feel quite as responsive as you might like sometimes, which is a big deal considering how much platforming there is, and how much of it consists of tiny platforms floating over bottomless voids.
