Demo Update #3 — Tiles & Vials Steam update #786812

I realized some players were getting stuck early on in the demo because the fights felt too difficult or because they put themselves in a sticky situation by picking a 3rd tile type right away. So I've tweaked the difficulty a bit, so it's easier to start out and made sure players don't have the option to pick new tiles for their inventory until they are a few fights in.BalancingLowered the difficulty of the first few fightsRemoved tile selection from the first few fightsContentAdded 3 new artifacts to help with board control
