For my final project I made angel bird! I have always been a gamer at heart and love competition whether it be beating my peers or my personal bests. Originally for my proposal I wanted to do scream go hero but had difficulties with voice recognition. Flappy bird was my backup and I am really happy with the way it turned out. I used my knowledge of objects to create the generative backgrounds and the pipes, and I believe my angel bird with a halo is pretty cute.

How the game works:

The game automatically starts and all you have to do is press the space bar to make the bird go up. Instead of scoring, you want to beat your personal best times as you want to see how long you can go without the dreaded “GAME OVER.” Enjoy!
