It seems to always save my progress. Is there no way to start from the beginning? Or go back to old levels?
I didn't understand the mechanics at first (beat first level by pogoing) which lost all my time. I get the concept, but I'm super lost in actually navigating the levels.
I always get two levels to work on, which I switch between with E? What about restarting, or jumping back to old levels? 'r' just sends me back to my current level.
