Many people had issues with the difficulty of the game. I worked with a couple of closed-beta testers on balance for the past weeks but it seems that the game is still a bit too hard.
Here's the first update trying to address this with the following changes:
Note: games you've already started before the update will still be in Normal difficulty. You can select Easy when starting a new game.
Please give me some feedback on the new easy mode: it may still be too hard but then, it may now be too easy. I did a test run without spending any of the gold I hard earned (>1k) and leveled everybody up to level 3 without any losses.
Hope this update helps out those who have been dying too much.
