Thanks so much and I'm glad you enjoyed despite the controls being difficult! :)
My original concept was to find a way to sync the jumping to the music but exactly how to pull that off is beyond me. As is you just need to press jump right as you impact with a surface - you actually have a quarter second buffer ahead of time and a couple frames after landing where it will work. Lacking a tutorial really hurt in communicating this though!
I had also planned on an optional feature to show little collapsing circle previews (like in osu!) as you come close to impacting a surface, but scrapped that just cause I knew it'd take quite some time for me to figure out how to implement. I still think that'd be a nice addition to keep in mind as I work on this in the future.
