Achievements added

Hello guys,

this is MACH Games. We updated our games and added the following features including:

- Achievements: Now you can achieve some achievements, which give you special image-badges

          One achievement also grants the player access for a secret door and skins for a special character. In the future we will also add a new map. So stay tuned.

- Some map changes (added some new meshes, tuned the lights, minor audio changes)

If you encounter any bugs, please leave a comment or contact us. Since we are two people with limited time we cannot find them all.

Sincerly,

MACH Games
