It's a straight flappy bird clone as you said yourself, does not go with the theme. That together with the upload time of your project...  Makes it obvious that this was a pre-build project.

Pre-building and guessing a project theme on top of cloning an existing thing completely defeats the whole purpose of a jam, you learn nothing out of it this way!
Please don't take this the bad way, it is meant as advice.

It is good to follow tutorials in order to understand the workings of an engine and to learn. However for a jam I would recommend that in the future you come up with your own ideas, that is so much more fun and I would have loved to see what your creative mind is capable of!

I really hope to see you again in a future jam with your own idea, I know you can do it!

It looks like this was updated before the Game Jam started and you followed a tutorial to copy a game and then just submitted it when the Game Jam came around. Game jams are suppose to be a fun challenge and I really encourage you to make a game during and for the Jam

the game is nice but it doesn't really fit the theme, maybe you could have added two birds that needed in two different heights. 

Cool game but I don't understand how it fit the theme.

I actually have an extremly simillar game based on poopy monkey.

Nice game! But how does it fit the theme?

I hope you can check out my game too!

Ah, I really enjoyed flappy bird! How does it fit "Stronger together?". 

Hi, just played your game and it was very fun, but very hard; I couldn't get past the first pipe. Just so you know, when you die and it comes up with the loose sign, you actually spelt it wrong, the only other thing was that I didn't really see the theme in it, nether the less, it was very fun and enjoyable.
