Just learning Unity, my kids had a blast with the collider demo I was making so I threw some sprites over it and here it is to have fun with!  This won’t likely be actively developed.  I still have to add a visual tracker of the birds you’ve missed (you can miss 10), and an overlay to  let you know what level you’re on.  Also required is dynamic screen sizing because in browser plays a little funny.
Have fun :).
