After LanokirX video a major glitch was discover.
-If you died after you come back from the dark mill the game will sent you back to the start.

This glitch has been fixed and the new build has been uploaded. Your saved game should be able to work with the new build.

-Also, the first dark mill level has been slightly edited due to a minor design fault.

Thank you all for your support!
And thank you LanokirX for catching that glitch.
