First I do not want to offend anyone to be clear.
Now it seems really absurd to me to organize a Jam if you don't have enough staff to play all the games.
In my particular case, I spent every day until the last, investing time in creating my game, I even made updates 1, 2 and 3 times, to perfect the game. and then you tell me that I depend on others to know if it's good or not. and with the wickedness of people today.
I believe that the voting system is poorly organized, I prefer that 2 competent people judge it over 40 imbeciles.
It seems to me a big mistake on the part of the GDevelop organization in general.
In other gamejams that I have participated in, there were about 1,000 games and they are only valued by the judges and if they do not have time to play, the evaluation period is extended, that is logical.
Nothing as I say is just my opinion, no intention of offending anyone.
