Me and my friend are aspiring Indie Game devs. and we're hoping to get some help. As the developer of the duo (him being artwork and music), I need to create a physics engine for the game. I am sure there are some out there, but I think building one will be best for me. If anyone could direct me towards a tutorial, book and/or any learning utility for this project, it will be most appreciated. Though it isn't my first choice, suggestions for 2D/8-Bit physics engines would be great (links, please?). Again, thank you in advance for helping.
