Hi everyone !
During the Molyjam, I worked 48h with 3 people on a game based on SFML, called Black and White and Colors.

It's a short puzzle game, where you have to get through a dozen of rooms. You have to change your own color in order to interact with other elements, each of them being connected to a single color.
The game is short, but very stable and polished. The only major problem occurs with the glowing effect on lights, which can be a bit strange/aggressive depending on the computer.
We were 3 programmers and 1 game/level designer. We created most of the assets ourselves : the graphics programmer designed all the sprites, and I mixed the soundtrack. The sound effects were found on the net.
We used SFML for the render, with a custom system of components tree (relative positioning, multi-line text) with multiple render pass, to improve shader usage.
The levels are xml-based.
We spent something like 30 hours on the architecture of the gameplay and the rendering pipe, then created all the levels and implemented the rules. The last 4 hours were spent testing and fixing everything.
Hope you'll enjoy it
