Love the cheeky name, but damn, you have to hit z to start, and it doesn't tell you to do that anywhere? That's rough, you might want to put it in the description at least, and as close to the top as possible. I tried two different browsers before figuring it out.
Other than that it's a bit of a mixed bag, love the artstyle, but not a huge fan of the music, great that you've implemented checkpoints, but those slippery platforms could use some sea salt on top. That said, you've got all that, two different movement styles, and cutscenes, and that's a lot of work in 96 hours.
