Regarding the jumping delay, I did notice a delay but I'm sure it was just normal input latency due to vsync. I'm used to playing games with vsync disabled to reduce latency as much as possible. It became noticeable because you have a timing based mechanic.
I never actually knew there was a tutorial going on except for the text I had read at the start lol.
I gathered from comments and such that there's a lot more to the mechanics than I was able to uncover in my blind session. It looks pretty interesting. Hope I can try out a more polished version in the future.
