I'm sorry to hear controls gave you issues. There was a red indicator for grab but I can totally understand if that wasn't a very clear indicator. I probably could have done something better for that.
For the jump being floaty, that was very intentional lol. I wanted that to be more of a casual approach to the levels, so I tried to make it feel more like gliding. But you can use the other jump by jumping right after you start running, that one gives you a lot of forward momentum.
Anyways, good job with the S ranks and thanks for playing!
