- You don't need to kill every butterfly
- With the "K" button on your keyboard, you can shoot without the need to click on the shoot icon
- You need to achieve the most points. I got mine at 39000, so you probably need between 35000-39000 points.
- Combos are your friend. Never kill one by one. Bigger combos, more points.
- If you want to cheat, a program called Cheatengine can slow the game down
