I liked it, The 1 bit color palette was good, the controls were good, some sound effects and musics would be nice, there was also little incentive to move left or right, maybe add in some hazards you need to avoid while slaying birds :)
I'm happy you liked the art style and the controls. : )
I also like your idea of adding hazards to encourage more movement.
Thanks again for the great suggestions and for taking the time to play. I really appreciate it, and I'm planning to keep improving the game after the jam!
