SPOILERS AHEAD
EDIT 2: Don't tell me exactly what to do, actually. Just tell me if it's intentional or not. If it's intentional, I'll still get a chance to play the game trying to get it to work on my own, and if it's not, you know you have something you have to fix.
How the heck do you put items in the Belt in Version 0.1.5??? I bound/remapped the equipment interface to the ` key and mashed the left Alt key and the mouse button over one of the incidentally greyed-out slots and I still couldn't get my artifacts in! Why can't I do it?
Is it because I have to buy the Belt from the shop? What???
EDIT: Just brought something and it turns out it was a hint. Just realised what I've wasted my DCoins on after spending some on Laura only to find out that all I purchased was an infobox when the premise of the game was supposed to be teaching yourself. Oh well, I guess that helps people who don't do that.
