Thank you :) I'm still working hard to get it finished.
"Jump to grapple" was originally off by default but I decided to change it because it seems to be to most intuitive way to play for new players. I know though some people like you would prefer to have it disabled. There's just no way for me to please everyone :P
I made a note to allow separate keys for reel in/out in the complete version. Umihara kawase conditioned me to the current control scheme, but I understand why it may feel backward.
I don't think it would be realistic of me to expect anyone to speedrun my games, so I'm not thinking about that at the moment :P That said, I may change it to reset the levels like you suggest for level design purposes. The current behavious was simply the easiest solution for the demo.
Big thank you for the feedback!
