Congratulations to your first game and your first game jam! Nice flappy bird clone. Some things to improve:

• Add somewhere a short description on the controls (even on the title screen is ok)
• Sometimes when you "flap" too much you die because the left border catches you. Not sure if this is by intend designed like that, but it felt quite unsatisfying to die like that.

Keep on making games!

I like the idea of the flappy bird fish haha. Also, the song is pretty good.

I would suggest a few things: I would be nice to have some kind of tutorial, even if it's only one key to press. You can write it on the description field of the game. I felt like the fish's  (or the sharks's) hitbox wasn't working very well.

It's an awesome first game! Congrats!
