- The Skelebot Giants now have a massive knockback to their melee attacks, letting them basically punt your character a few screens away.
- Put in a number of improvements to the visual display and functionality of the direct keyboard targeting.
- The ranged bosses can now hit you from further away, making it harder to kite them.
- Gem veins and other mine-able stuff underground is now easier to find and see, and the dungeon map now updates its colors to indicate ones you've already mined.
- Support for single-button mice has been improved; actually, so has support for mice with more than three buttons, too.
