Bug preventing final ending is now patched

The Iron Cloud transitions from v1.1.0 to v1.1.1
Several things has been changed:

• Interactable object responsible for the final ending is no more being blocked by invisible wall
• Endings received multiple times can now be skipped
• Progress is now properly being loaded from %Appdata%\LocalLow
• Controls for vertical movement are now being shown when capable
• Unused objects has been removed from scene to optimize the gameplay

Also added some effects to cover image to attract more clicks, because I assume 0.8% CTR is poor.
