I never tried doing it with C and OpenGL! Huh. I did, back in the day, try making engines in C++ and Allegro for DOS. That was a really fun library to use! I will say this, I'm not going quite that low level, so I don't have to worry about object placement quite as much, thankfully.
Thanks for your comment! And I'm so glad you're looking forward to the game. This one is a bit of work, but damn, it looks good.
