It wasn't your fault or the jam theme's fault that the theme wasn't fully adhered to. It's a common problem across all jams, one I've unfortunately seen far too often. Many submissions serve solely to generate publicity for the participant's own game and garner attention. Some of these projects are so old they're gathering dust, even though the rules state that they must be created within the jam timeframe.
I understand your frustration. I think you really had some bad luck with the submissions this time. Nevertheless, you could still thank those who actually dedicated their time and energy to this jam, instead of just admonishing those who don't follow the rules.
What it's really about, though, is pursuing your passion. If it didn't work out well this time, maybe it will next time. Don't expect fame or fortune. Do it because you enjoy it. If some people don't follow the rules, it's certainly not your fault.
I understand your frustration. The only way to win is to try again after a loss.
My project was created specifically for your Jam. That's what I always do. Even though there are no prizes, I hope you appreciate my participation and maybe even a small smile :) The Canadian flag for the language selection wasn't a coincidence, by the way. I only chose Canadian English in the text-to-speech generator for you. I don't know if it differs from the general American style of speaking. My English comes mostly from Google Translate.^^
Without your Jam, I probably never would have had the motivation to create a humorous project. I simply don't have the sense of humor myself. At least it gave me new perspectives and helped me improve my animation skills a bit with the characters.
Good luck with the next Jam. Maybe I'll participate again if the opportunity arises.
