Hi Ilias, thanks for your feedback and recommendations! This game was created on the Unity engine, 3d graphics were created in Blender. The game has been optimized, this can be seen from the weight of the game at 23 megabytes, the game does not have complex control algorithms or any shaders that can affect performance, we also used Batching, that is, we combined objects with the same materials to reduce the number of draw calls, and to increase performance, as few high-resolution textures and complex multi-poly meshes were used as possible, and as for the code, we optimized the code: during scripting, I tried to avoid excessive use of loops and complex operations in loops, and also optimized memory requests and resource accesses. You can find out more about how the game was created in this video (you can turn on subtitles in English):
