1.2 fixes and secrets

Fixes

- the player now flips on the first level

- the platform at the bottom of the water on the second level is now on a higher layer than the water so it does not appear on top of the      platform.

- rocks piling on top of each other could block your path so made them despawn

- various smaller things.

Features

- can now alternatively use wasd instead of the arrow keys so you dont scroll down whener mining rocks.

- new secret room on last level (hint: to the left).

Optimisations

- Halved the size down to 26mb for faster loading etc.

I probably missed some stuff but those are the major changes.
