- Level 6 rework. Should be easier to platform with the gun to get 3 sharp stars.
Also minor changes so it's harder to get stuck around targets.

- Add oil to level 8 so if you choose to get the last target from the right, it should feels smoother to get.

QOL

- How to play page added.

Fixes:

- Rework of all the collision shapes

- Fix bug where you could add multiple score with the same name display on the screen.
You should only register the highest score. So you can't have multiple score with the same name.
