Very glad you enjoyed it so far! There's a lot more to come as well, and I will be updating the demo more in the future. :)
Also, there are some tips the game currently doesn't teach you, like the kick move in the air that'll allow you to get a boost on your jumps. And stuff like longjumps and backflips. As I noticed you didn't use these in your video, and they're very useful!
That said though, the somewhat lacking tutorial is mostly to blame for that, haha. It'll become a bit more extensive in the future!
