I feel like I can barely even control this, but I've played, like thirty games? So... good job.
The connection to the theme feels a bit stretched. The idea of sacrificing your limbs to gain jump speed is interesting, but I don't think it works yet because it usually just happens by accident (see above about the controls!) and, at least in the web build, the boost is so big that I never survive it.
Overall, though, I had a lot of fun. Thank you!
