Play Online Platformer Toolkit
Platformer Toolkit gives players simple controls to fix movement and collision issues in platform games. You move sliders to tweak jump height, gravity pull, and walking speed. You test each change with a single click and see how the character responds. It stays focused on one problem at a time so you never feel overwhelmed.
You open any level from a list of templates or upload your own design. You slide controls to shape character moves. You press play and watch your hero run, jump, and land. Each test shows where timing feels off or collisions misfire. You adjust values and test again until the motion feels just right.
This toolkit does not turn you into a full game maker. It leaves out art creation, sound mixing, and coding features. It focuses only on quick fixes and small adjustments. Anyone can launch it online without downloads. That simplicity lets you solve issues fast and move on to the next project.
