The cube mechanic was a bit too clumsy. We reworked it for a better experience. You can now pick/drop the cube with a left mouse click or cross button on your gamepad.
Here is it in action:
With the new cube manipulation, we also had to move the art piece in the Stonehenge.
There was also inaccessible art piece in the Planetarium level.
We also tweaked various sound effects, visuals and some puzzles.
And few bug fixes. Thank you for reporting them!
