I do not think that it is a critical error.
It is just a good proof that you did not used any game engine that comes with many MBs for the runtime. Like Godot or Unity.
???
I'm having a lot of trouble trying to understand what you're saying. Is it the game engine I used or is it because I did not use a large program to create the game?
Because if this is a GB game then it will be just few kb.
