Log output

After the developer opening, the game tries to reproduce another video. You can
hear the sound playing, but the video fails to load. The game seems to try to
load the video again and finds itself in a failing loop, leaking memory.
While trying to reproduce the intro video, the game spams to the log:
> fixme:mfplat:media_source_get_service_GetService Unsupported service {dd0ac3d8-40e3-4128-ac48-c0add067b714}.

This issue (memory leak) doesn't occurs on Proton, but the intro video still
can't be reproduced.

Procedure:
1 - Open up the game
2 - Wait until the first intro (Massive Monster opening) ends
3 - Watch for the system monitor that RAM is leaking. Kill the application or
else it'll freeze your system

Game is paid and can be downloaded from Steam or GOG. Their official page:
