Since the release of the Early Access 0.1 version I have been listening to your feedback and have made the following changes to the game.

Improvements:
-Added signs in the island to help you navigate to the levels (this may just be temporary since the island isn't finished yet and if the player misses the tutorial tour from the beach).
-Added a "Respawn" button in case the player gets stuck. It can be seen in the Control Mapper and can be activated via "0" on keyboard or left-centre button on a gamepad.

Fixes:
-Patched up area in rocks where you can get stuck.
-Unlockable credits portal functions properly now.

Thanks for the feedback!
