If you are planning on making a game out of my Xephyr physics engine, read here:
Get permission from me, tell me what it is used for, if you need help or not, for what you would need help with, and last but not least, I may give you permission. But, you will need to follow these 3 simple rules: #1: Use the Xephyr logo in your project and notes. #2: Replace sprites, copy code and move it around, and use other peoples sprites as necessary. Don't say I didn't warn you. #3: Have fun, and most importantly of all, credit everyone else for usage of anything other than what YOU, the remixer, adds yourself.
