(As this is an enhancement not a bug, I don't think i need to provide too much information.)
Although enemies in Super Mario don't have such animation either, as a more elegant platform game, it is better to add animations like kicking Tux when Tux collides them, because it can make the enemies more vivid.
From the comment in SDL_filesystem.h: Please call SDL_free() on the pointer when you are done with it
When building the project with MSVC, I ran into some debug heap asserts early into the program startup.
The culprit appears to be the code in m_config.c that does free(prefdir) as changing these to SDL_free(prefdir) resolved the issue.
Modify the setup.py so it produce bdist_wheel for manylinux including the libgraphqlparser.so/a
Modify the build process so this wheel is uploaded to pypi
Modify the cffi part of tartiflette/parser so it loads this lib instead of the local one.
In particular, when a rare enough event occurs near the start of your game, consider adding a tutorial hint explaining it. For events that occur very often, if the message is long, it should instead be restricted to the first (few) occurrences. Depending on the case, this may or not may be easy to do, so may require a separate ticket (please open, as needed).
