A fun rock falling concept! I felt the increment of difficulty was ok, and I didn't find any noticeable bug. I can see lots of potential adding some music and animations when the flamingo is hit by the rocks. Overall looks a good game! Good work! :)
thank you for playing and thanks for the feedback and kind words! i have noticed that sound effects/music are a very big thing to the player experience and making it more polished, i think that's my next thing to learn!
