I am inclined to think there should be a limit to the number of planes on screen at once. Having ~6 planes causes lag and death for an unadapted flock. Still love the concepts, great job so far.
This game is much, MUCH too difficult towards the beginning. It is TOO hard to get off the ground. Enemies (chickens, crows, berserkers, more specifically) should be weaker towards the initial waves. However, once you finally and masochistically grind through and earn medals, your way becomes easier. This would be infinitely better if it was more easy for a new player.
I would like to be able to scroll whilst slashing. I gets kind of annoying slashing towards the edge of the screen while there are enemies you can't see lurking and waiting to kill you.
