Nice take on the flappy bird game!
unrealated to the game, i would sujest to take some time and create a thumbnail for your game and maybe some screenshots, it may seem less important but it really is.
good job!
When you upload the game to itch theres a box you can put in the thumbnail and bellow it theres a button for screenshots, if you want you can even add then right now! it will still show up in the jam page. just click on "edit game" on your game's page then add it there, ive added screenshots to help.
