Platformer Toolkit

Platformer Toolkit shows how dozens of stats separate Inside from Super Meat Boy. The tool lets you change a platformer character's stats and watch the feel shift from the slow, weighty movement of Inside to the sharp, fast movement of Super Meat Boy.

Mark Brown uses it in "How To Think Like A Game Designer" to show that a game has hundreds of mechanics that interact, overlap and can contradict each other, so designers should check that their mechanics do not undermine each other. In his words, "these mechanics interact, overlap, and can even undermine each other."

Platformer Toolkit has a camera panel for tuning 2D camera feel. The panel lets you adjust damping, zoom, lookahead and whether jumps are ignored by the camera.

It appears in Game Maker's Toolkit's "How to Make a Good 2D Camera" as a hands-on way to try these camera settings.
