Your flock moves slowly when close to the mouse, and faster when the mouse is far away. Makes tight movements hard. Please make them move at full speed and stop on a dime at the mouse, same as most top-down shooters.
As far as the code is concerned, the hitbox is 0.5 pixels. And plasma is intended to be a high-risk weapon. Don't use it if you can't get close enough.
On movement: You decelerate as you approach the mouse. This makes dodging and tight movements really hard. Please make it so you move at full speed and stop on a dime when you reach the mouse.
I keep wanting this game to be good. It could be if you just playtested it and adjusted the numbers for damage, armor and hit rate. Tip: If you want people to buy your game, make the free version fun to play.
Please don't change the name of the file when you upload a new version. That makes the old cookies not work, and erases our saves, and makes people give up on the game.
Great Tip! When you can afford it the Rump Roast upgrade is also Pigtacular :)
