This is a new engine, we are developing for a MetroidVania-like game to be named.
The code-base is initially based on Rockbot engine, but because we added new tools, libraries and methods, it will be mostly replaced. For example, the whole collision system will now be using Box2D and map edit will be made trough Tiled Editor.
We also will move from Qt creator as dev tool to C-Lion with CMake, as seen in the screenshot above, that should make life easier when porting it later on.
The version of SDL will be upgraded from 1.2 to 3.4 or later, that should get better performance and code structure. The dependency to this library will be also encapsuled, meaning we can later change to another backend on systems that do not have SDL or a different version.
