Nice to see another Raylib user in a game jam!
The game itself was quite fun and challenging. Having to balance between timing my whistles and the onslaught of falling trash made for an engaging gameplay loop. I think what can help though is having instructions on how the controls and mechanics work either in the title screen or maybe in the description of the page. This is because admittedly I was confused at first as to what I needed to do in the game until I clicked on the whistle at the bottom right.
Good job!
