The True Slime King is a single player hardcore puzzle platformer with a focus on tight controls, challenging maneuvers, and mind-bending puzzles. All of this is achieved with just three buttons: left, right, and jump. Use your sliminess to stick to walls and cling to ceilings in order to avoid obstacles and reach hidden items. Whether you're a speed demon crushing records or you're just interested in progress through the story mode, one thing is guaranteed: you will die a lot in the process. But don't worry, you'll be respawned and back in the action just as fast as you can die.
