This is a simple flying simulator with a little bit of a game embedded in it. Use the arrow keys to control you. Try and touch the hearts and you'll get a point for your score. Don't hit the tree or the buildings, because you'll get a point knocked out of you!. The hearts are mostly near the clouds. I'm going to maybe work on this a little more if it needs it. I used the "Make it Fly" tip and after a little while, going to add it on the Things to Try. I'm going to right away put in the Make it Fly studio, though! P.S. I'm aware of a glitch where the tree, when it reaches the left side of the stage, it waits for the building to catch up before respawning.
I used the Make it Fly tip with some mild changes for my liking. Thanks to @maggylizzy for the "magic trail". The rest is my work. If my project is in some way similar to yours, keep in mind that is entirely coincidental.
