Wow, talk about the arcade feel. You definitely nailed it with the oldies arcade style. I have some feedback for you!
1) The game was a bit easy but didn't really stop me from enjoying the visuals / music / atmosphere
2) The bird on the desert level all the way onto the right of the map behind the door started chasing after me even when the door was closed but maybe that's an intended mechanic!
Overall, great job on finishing a complete game and stylizing it so gracefully
