The concept is awesome! really unique :)
It took me awhile to figure out that the sliders change the speed and jump height of the character, but there is much potential for future puzzles with this mechanic :)
Some recommendations:
- personally feel the gravity could be a little bit lower (so the jumping took more time)
- add some Coyote Time to the jumping
- use a rectangular box for collision on the platform, the text collision is sometimes frustrating
Great work! love it :)
