Firstly, really excited to finally see this release.
The one major bug that I found was in the reach of the killaura did not extend beyond 4 blocks.
The other one was the speed was only applied when the player was airborne.
Some quality of life changes that I suggest

• Making the menu easier to navigate (with the mouse perhaps??)
• adding key repeats to adjustable values so that you can just hold the button to increase or decrease
• world icons
  Modules that I would like to see
• x-ray
• reach
• mining???
• hunger if possible

Thank you and I look forward to future releases
