- Added a new dynamic difficulty system. The game now automatically adjusts the difficulty between floors based on a variety of factors, mostly relating to skill level. This feature is subtle and will generally have the biggest impact on players who are either very good or very bad.
- Dynamic difficulty does not affect the abyss, instead abyss enemies now become stronger over time.
- Added new special cards to leveling. Special cards are rarer than the standard weapon and stat cards, and include upgrades to bonus chance, rerolls, boosts, cursed cards, powerups, and more. More special cards will likely be added in the future.
- Reroller can now be upgraded to tier 5 in the shop menu.
- Reduced EXP needed to level up.
- Various other minor tweaks and bug fixes.

Note: Will probably be tweaking the difficulty system over time, post your feedback if it's giving you trouble. :)
