Gridity is a fast-paced shape matching puzzle where the main role is played by gravity, and *you* are the gravitational field. Move the gravitational field around the spacetime grid and grab matching shapes: get close and dislodge the shapes from their positions with gravity, while avoiding all arrows. Arrows always fall towards you: if they touch any shapes you've grabbed, the grid will reclaim all shapes, and you'll have to grab them again. Once you've grabbed all shapes on the grid, you'll have to survive the arrows for a few more seconds in order to clear a level. Key features: • instant launch: zero loading sequences • play with one finger: no controls to learn, just tap and pan • zoom anytime: tap on shapes after activating the gravity field • haptics feedback: feel what happens on the grid • unique levels: never play the same level twice • choose difficulty: switch from easy to normal mode and back, as you see fit • Game Center: collect achievements and compete in multiple leaderboards Details: PLAYING: • Collect all geometric shapes on the grid, by making them fall in a gravity well — you are the gravitational field itself. • All shapes are attached to the grid: in order to grab them away, move the field until they fall into it. • Avoid the arrows you will find: these are *not* attached to the grid, so they keep falling towards the gravity well at all times… MOVING: • Touch the grid to activate the gravity well — if you tap on the arrow or on a shape, the field is only disturbed. • Pan with a single finger to move towards any shape — you can also start panning without tapping: it's actually better to keep your finger away from the field, and lift it as needed. • When a shape is close enough to the field, it will fall into it and become “grabbed”. GRABBING: • Keep collecting any shape of the same kind remaining in the field. • Once you have grabbed all shapes of a kind, you can choose any other kind — until there is no shape left. • Once all shapes of all kinds have been grabbed, hold on for a few seconds (if you can…) in order to complete the level! STAYIN’ ALIVE: • If you have grabbed a circle, and by accident you grab — say — a triangle, you'll lose any already grabbed circle(s). • The arrow is your enemy — as soon as the field is activated, it will start falling into it. • If the arrow manages to fall into the center of the field, you'll lose all grabbed shapes and have to restart grabbing from scratch…
