I really love this game, especially the 3D world! The hook shooter is a great idea. Sent some support your way because of how how much I've enjoyed playing it.
Any chance of getting a permissive license(MIT, BSD, Apache, CC0, PD, etc.) on it in github? I'd like to study code and mess with it myself but I don't want to run afoul of your copyright. If not, no big deal!
