Really cool little game, it reminds me somehow of Antz. I really like the variety of enemies and that all had a different designs to them.
A feedback on the implementation of the enemy bird will be to make some kind of sound or animation or even movement before they about to attack in order for player to know and dodge. I dodge it every time, because I was counting on my head 1.. 2.. 3.. 4 and then dodge.
Overall really good game! Congrats on your Jam
