Wonderful job for a first jam entry! Getting a game done on your own is really quite impressive. I really appreciate the tutorial baked right into your entry to the map and how it explains all the things needed to get up and going!
I do have a few nitpicks regarding the jumping. When jumping I sometimes wanted to go up high but timing the jumps together was somewhat finicky. Also when trying to land on some of the super thin platforms I would try and glide down onto it. However if you do this you have to rapidly tap left and right to not overshoot some of the platforms while holding space to keep gliding. Then once you land you automatically jump off the platform cause you are holding down the jump button lol. It would have been nice to have jump be bound to when you pressed the spacebar down rather than just having it jump if the player is on the ground and the space button is down.
That said, the little hop your bird does to walk around is so cute! I also really liked the simple but really effective gameplay shift that happens once you get the :cherries: For your first Jam this is crazy impressive, seriously well done!
