Small twitch based platformer I made to familiarize myself with Pico-8 coding.
Left and right arrow keys move the character.
Up arrow allows the character to jump, either holding the key or pressing the key once more in the air allows for a slightly less powerful double jump.
z allows the character to grapple to a green block. Hold z to remain grappled.
The grapple hook is designed to emulate a spring, by pressing left and right the character can swing, by pressing the down arrow key you can tug on the rope to help build momentum to reach higher areas.
Feedback is welcome and much appreciated.
