Dude, its good to see you on itch! I used your kit to learn from like a year ago!
If you want you can check out my prototype..
The character is a custom character controller..
All built from scratch and with some well gained knowledge from looking over your project..

Gotta admit, when I first looked through it I didn't know about prefabs.. Why the player was spawning in, how interfaces functioned or what they even were.. I've since learned a lot.. And your project helped a lot!
This guy is solid!
