The image is from my first complete game called Sliders and was
developed using Visual Studio 6 and OpenGL. The audio is handled entirely
by the FMOD system.
Development from concpetion to completion was around 2-3 weeks. The
biggest issues faced came in the form of making sure that the boards don't
start with a ton of matches from the get-go. It would seem like a simple
logical problem to fix, but a surprising number of bugs arose from the
'fixes'. Chalk that one up to incompetence. The graphics are pretty
straightforward using Orthogonal projection and some wrapper functions that
take the information about the sprites and compile them into the necessary
vertex arrays to speed up rendering.
If you ever wanted a reason to use FMOD this is it: I tried every audio
system I could find, and they were all either too limited, too complicated
or too pricey.
