Improvements

User Interface & Visual Feedback

• Crit damage is no longer shown on the player stats

Unlocks

Weapon & Combat Mechanics

• Many weapons now have special descriptions (e.g., piercing)
• Special bullets now have more synergy with items, abilities, and weapons

Menus

• All menu options like class, difficulty, and map are now remembered when returning to the class menu

Explosions

• Explosions still don’t damage the player as intended, but now push the player based on distance and intensity. Players must be more cautious when detonating large explosions nearby due to the risk of being launched into dangerous positions
• Explosions now have a minimum range regardless of damage, ensuring even low-damage explosions affect an area
• Slightly increased the size of explosion particles to better match the area they cover
• Explosion screen shake now scales with explosion size

Bullets

• Bullets now have some random speed—some weapons have more bullet speed randomness than others (e.g., shotguns)
• All bullets can now pierce if they deal 4x the target’s max HP, making high-damage, low-DPS builds more viable

Game Balance & Mechanics

• Day 15 length increased by 20%
• Difficulty 1 is now 20% harder
• The default difficulty is now Difficulty 1, not 2
• Game starts 50% easier, but difficulty scales 15% faster

Armor

• Armor is a new mechanic that reduces all damage by 1 per armor point (minimum 1 damage received)
• Armor also slows the rate of tick damage from effects like fire, toxic spit, or axes

Knockback

• Improved knockback for enemies and the player. Knockback directions are now calculated separately for x and y, resulting in more intuitive behavior. Previously, a small push from a different direction could completely override existing knockback

Lighting

• Toxic puddles now emit green light instead of the default yellowish one

Enemy Changes

General
