Hi! We just released our first game, developed from the ground up using C++ and OpenGL without the use of an existing engine, and Blender for the models and animations. It's a little  game about penguins and ice skating, in it you collect candy canes while evading the penguins and their shenanigans. Here's a bit of gameplay:
