Thanks for the feedback! Haha love the screenshot!
The ducks are spawning randomly at the the of the screen so it can get quite difficult. Now that I think about it, maybe it would have been best if I stuck them in a cage instead? No? :D
Sadly I only had two days to work on this so I didn't get the time to add more enemies. I would've loved to of added something like skeletons or some sort of flying enemies.
....Wow wave 50! I don't think even I played it that much haha. Glad you enjoyed it!
