Hi, thanks for the compliments. Yes, I noticed the sliding too. The white in black was the missing tooltip that should indicate to the player how to pick up the gold. However, this was eventually not implemented (says: RMB) and you have to stay over the gold for 3 seconds.
It helped that my artist wanted to help out for the jam (he has a lot of other stuff to do for QL, but together we were able to provide a MVP mostly. The storyline wasn't fully in, as the player doesn't know he will have to play the game atleast twice (to understand the way 'not all that glitters is gold' is part of the game).
