So this is bird assassin. there isn't really a lot to it but its a fun little game.

All Weapons insta
First off i only know 1 big "cheat"/"hint" in this game.
all you gotta do is play the tutorial cycle all the weapons and the next map you play will you have all weapons. you might have to go into the shop or something i dont know but you can get all weapons by playing the tutorial.

Ultimate tip
KILL THEM BIRDS!

There isn't really alot to this game so there isn't need for a big guide. hope the weapon trick helped have a nice day.
