I played the game in 3 bursts of time (around 8min each), managed to finish it only on my last try with a 6 minutes run.
I was actually about to review your game as too difficult for me when I read the comment "mid-air contol is too op" and thought "wait, what", and decided to try it again. Lo and behold, I was playing without ANY air control and the game was absolutely difficult before. I noticed that this is actually explained in the beginning, but it wasn't clear to me when I read it (and tbh I'm the kind of player that ignores most of any text that has more than 4 lines in a game).
So WITH air control, the game felt much better to play, black holes felt less random (I could recover after getting sucked into a Black Hole), and I could break momentum from a far away throw so I could land safe on the ground. Overall, the game was much more enjoyable unlike my previous tries. And I like the fact you can only Air Control without any energy; it's kind of a risk and reward feeling, using all your energy so you can wiggle a bit in the air to land safely, or try reach the next platform and risk falling.
My only nitpick with the mechanic is that it didn't felt intuitive, or something that I was able to do from the start. Bear in mind my potato-ass Gamer(tm) brain that hates instructions, but rolling on the ground isn't something that you do from the start (launching yourself horizontally is MUCH faster), and rolling in the air doesn't actually work until you have no energy AND there is the slight cooldown after you launch yourself upwards for the last time for the air control to kick in. The mechanic itself makes total sense in the game and was the difference (for me) in it being enjoyable or not, but if you ever with to develop the game further, my suggestion is to make this mechanic clearer (although I'm really not sure how).
Overall, really good game, a simple and fun mechanic, and a good level for speedrunning and plenty of punishing/recovery moments.
