This game confused me at first because I think the aiming is terrible, but here’s how its done.
Hold down the mouse button to gain power as you step in front of the petpet. Remember – it’s not where your cursor is, it’s where the Kyrii is that makes the petpet sail strait. Stand directly in front of the petpet and release your mouse button when it is in the red. If you release it when the power meter is ALL THE WAY full, you’ll get one berzerk point. Get 3 berzerk points, and you will go into berzerk mode, which stops the time and makes the Kyrii always throw full-strength.
