This game is great! I love the concept!
There are two programmatic bugs that I noticed, but they are minor.
1. The player the player is up against a wall where you want to jump up on, the player gets stuck if you are pressing forward as you jump.
2. When on a moving platform, the player doesn't go along for the ride. It feels a little awkward that you need to inch the player along with the platform as it moves.
Again, this are minor issues that can always be worked out, so I'm not considering them when I rate your game. But I really like this game idea. If you plan on updating it or turning it into something bigger, please let me know.
Really nice job! :)
I'd love to hear your feedback on my game.
