Impressive that you pretty much covered every base of the information loop with your new features, I liked that! Just enough feedback to class as placeholder, everything had some response on screen.
The new features show some good technical knowledge and felt well designed (thanks to the added feedback).
There was some clever but punishing level design in there, though, and definitely not something that was readable to players. The two major issues were the " single jump and dash" coming right after the "double jump" - players will always be inclined to repeat the behaviours they just performed, so I wouldn't be surprised if most didn't immediately double-jump dash and fly off the back - and the clever-but-tricky "jump inside the big tower" bit in the middle, which relied on me having looked at a spot that my eye wasn't drawn to as I went past.
Definitely a good start to your game making career! :)
