Manifold is a physics-based action/puzzle game created by artist and designer Joel Esler. Use special orbs that can alter gravity within a small radius to climb your way through dangerous situations. It's a simple idea that's been paired with smart artistic direction to create a game that pleases the senses as well as your sense of fun.
Control the bug-like character with the arrow (or A, D, W) keys and use the mouse to move the pointer. The cursor allows you to create gravity wells by aiming at a target then dragging the mouse to indicate gravity direction. The character will toss a ball that will open the gravitational disturbance when it comes in contact with a wall. You can create as many wells as you have balls to toss and can re-absorb unused areas by moving the cursor over one and tapping the spacebar.
Gravity bubbles don't just push you in a certain direction, they actually shift the gravity within the sphere, allowing you to walk on walls and ceilings inside its borders. This opens up a huge range of possibilities in terms of action and puzzle situations, and Manifold's levels force you to get pretty creative with your gravity-defying skills.
In later levels when you have more gravity orbs to throw around, things get really interesting. You'll find yourself suspended upside-down on a ceiling with saw blades buzzing below, the only thing keeping you alive being the chain of gravity wells you're constantly creating and absorbing. Just enough thrills to keep you glued to the keyboard for the next level.
Manifold has a very clean look thanks to its simple but tasteful design. It's an excellent example of pairing artistic vision with great gameplay to craft an experience that's truly worth your time.
Cheers to Charles for suggesting this one! =)
Due to popular demand, Joel has released an update to the game with more levels, some of them quite devious in design!
