Platformer Toolkit

About

Platformer Toolkit lets you tinker with the building blocks of 2D platformer movement. You adjust variables like jump height max speed and collision settings then test them in a sample level to see how they feel. The game turns theory into practice by letting you tweak over 30 parameters that shape how a character runs jumps and lands. Each change feels like a mini experiment in game design with immediate feedback as you play through the same short course with different settings. Players praise its clear no fluff approach to teaching core mechanics. The toolset is straightforward but deep enough to show how small adjustments ripple into big changes in gameplay. Available on PC Mac Linux and web it requires no prior design experience just curiosity. Many say it’s one of the most hands on ways to understand why platformers play the way they do.
