I can't really complain about this. What it purports to do, it does well, and though I feel that it's sort of boring, it's how it's supposed to be. 5/5 and respect.
This script uses the microphone button to jump. It will only allow you to jump while on the ground so you can't go flying across the map.
Be sure to this host with microphones off.
Version 1.1: Now makes a grunt sound when you jump and has cleaner beginning text (uses overlay instead of print).
Version 1.2: Now the microphone wont interfere with the sound. This should be the final version.
