I'll admit I was a bit frustrated at first with some of the levels, but as I kept trying them I noticed that the solutions were usually a lot easier and simpler if I just stopped to think them through
The enemy lock-on is pretty unique---I think my only feedback would be to somehow make it clear that that happens before you have to use it (though arguably having to use it will teach the player the mechanic one way or another), and maybe also to make the kill barrier at the bottom just a bit further down as having it so close gives you less time to attack while falling through the air (which could otherwise save you due to the generous lock-on)
Anyways this game (and honestly a lot of your other games too) has a surprising amount of depth in the movement mechanics for how outwardly simple it seems, so great job with it overall!
