Cool game! I got to the 4th round, but didn't have time to collect the bones to fight off the bloodthirsty ducks :).
It would be good to add a description of the controls to the itch page as well, since I forgot how to open the store, but I still remembered however, I liked the store - good mechanics!
I'm not sure, but I assume that the appearance of evil ducks is random by position, I would like to have a save zone for the player, so that the enemy doesn't appear right next to you and you take damage.
Congratulations on your first game, it was fun!
