I came back to play. Wow this game is neat! I wish I had a controller for my computer because using WSAD and Arrows together was a challenge--but that is on me, not you. I liked the jumping mechanic, the difference between min and max jump was a perfect balance.
Suggestions I have for you: 1)Set the background music to loop so that it doesn't end after a certain amount of time. (At least it did end in the browser version) 2)It was very challenging for me to stay on the moving rocks using WSAD and Arrows. Perhaps once on them the player should move along with them? -- I understand the way it works may be by design, however, as I do know there are games that use this mechanic. It was just hard for me.
Overall really fun game. I like the highscore feature too, that increases replay-ability for sure. I haven't beat you yet!
