In regards to the eagle screech, the two best options I can think of is either have multiple different eagle screech audio recordings (which is probably really hard in this particular jam) and randomly play one of them every time the eagle spawns. Alternatively, you can use the same audio, but maybe pitch it higher or lower randomly so it sounds different than last time it played. You could also mix both options for the most variety.

Thanks! I've just watched some of your stream. I think I will implement some code to make sure the coins don't spawn on top of the obstacles, however in play testing (since I implemented pixel perfect collision with masks) it was possible, yet challenging, to collect the coins and hearts that spawned on top of the obstacles. You had to utilise jumping at the right time.
