Invader Game 1

This is my first game on this website. Move your mouse to aim. Press space or click to fire. Press b to launch a wall. Dont let the enemies invade the base. There are 5 enemies in this game. Normal enemy (red) Most common to spawn. Fast enemy (pink) Moves fast. Multiply enemy (dark red) Spawns 3 enemies when hit. Leader enemy (yellow) Spawns 5-10 enemies when spawned Shield enemy (blue) spawns shield when spawned [when the shield gets hit, it shrinks your bullet.] I hope you enjoy it. And please...
