For the purpose of this project, a grunt is a sound registered by the microphone, making the Scratch loudness reporter block return a value of 50 or more. Make sure your microphone is on, and that you've allowed Scratch to use your microphone. Press any key (or grunt) to start, then just grunt into the microphone to jump over the obstacles.

Thank you @Griffpatch for the awesome Ragdoll Physics: https://scratch.mit.edu/projects/356286226/ Thank you @-Rex- for the awesome PTE: https://scratch.mit.edu/projects/276672672/ Thank you @RokCoder for the awesome tutorial on how to make a cloud leaderboard: https://scratch.mit.edu/projects/405031187/ (the code for the leaderboard in this project is all me, but inspired by his tutorial project). Music is Brazil Samba from https://www.bensound.com I didn't feel it necessary to remake the thumbnail, except to put the new name in there, so the guy is still jumping over a capital A, rather than a rock. No cats were abandoned in this project.
