Rktcr

Rktcr (from "rocket car", pronounced /ɹktkɹ/) is a physics-based side-view action-platformer-turned-puzzle-platformer; that is, it's an action game meant to be played thoughtfully at much slower than real-time. Rktcr is tool-assisted-speed-run: the game. Players can see the future and control the flow of time, allowing them to play frame-perfectly. Paths through levels can be easily shared, for boasting or collaboration. Rktcr contains 37 challenge levels, ranging from easy to impossible; and 31 world levels, algorithmically arranged into 300 worlds of varying complexity. All told, there are more than 1600 paths to discover and optimize.
