I enjoyed, nice atmosphere. The core challenge I see for this game is that there is no driver to make the player engage with the core mechanic (that the flock is multipurpose). Because the goal is just collecting a given flock size, I found it faster to never shoot, and just dodge the incoming attacks. Is one of those 'players optimizing all the fun out of your game' traps. Worth giving some thought if you make an updated version post-jam.
All in all though, I had fun, nicely done.
