I wasn't interested in this from the description, but then I happened to see a youtube video of it, and now I'm throwing it on my mod list to play around with a bunch more, because after a quick test run it might be my favorite Thok replacement?
It's possibly a little overpowered, but it's basically a combination of jump thok and rebound dash, with a big bonus for using it at high speed and some EXCELLENT game feel and sound design for the high speed version.
That little "tink" and everything stops a second? Love it.
