    Small update 0.5.4

    List of changes: Shards are now also given beyond wave 100 (to give to the friendly wizard) You can now re-arrange items in inventory by dragging When a recipe is active in the tower, all the inventory slots will be green The items in the wizard shop now can only be bought once The amount of shards you receive is more variable, but buffed in the end. The Archangel boss wave now end when you defeat all the enemies spawned during the wave AND by killing the boss Certain recipes would suppress certain stats (like Fire Storm would suppress burn from it's items), this has been removed for the stats. The effects of the items in a recipe are still suppressed (like the effect of Lit Match in Fire Storm) Frost Gold per Kill value is now consistent in both the in-game description and progression description Fixed a bug where enemies that entered your base did not get instantly killed (because enemies at very high waves had a lot of health) which resulted in them dealing more damage to the base instantly killing you. Fixed a bug where slow could be higher than 100%, which resulted in the enemies walking backward x) Fixed a bug where the drones could case an error, which resulted in more errors (happened when you switched a drone while it was shooting and that shot would kill an enemy) Fixed a bug where red random items would sometimes give items of lower rarity Fixed a placeholder text bug Fixed a bug where sometimes too many tree were rendered which caused an error for the dropping leaves visual effect Hopefully) Fixed a bug where the dutch language would show up (while it is not fully translated yet)

    Update 0.5.3

    Fixes and changes for update 0.5.3 - The friendly wizard now will keep on providing you items for shards after wave 100! - The critical strike damage of Head hunter now works with lightning tower scaling (and all other scaling) - Adjusted the scaling in endless mode. Wave 1000 should be much harder to reach - All endless enemies with the modifier Regeneration should heal now - Changed the descriptions of some achievements where the description still said some old information - Changed the description of the gold amulet achievement. The items have to be in the tower inventory! (that's how it worked but I but a wrong description in the achievements) - Resolution of items in tower inventory is restored back to before previous update - Fixed a bug where you did not get the achievement of unlocking all modifiers if you first beat two-lane hardmode, then one-lane hardmode (while having all requirements met) - Fixed a bug where the game would freeze for seconds to minutes when unlocking either the lightning tower abilities, or the spike tower ability - Fixed a bug where if you had too many lightning towers and used the Lightning Focus recipe, the amount of lightning strikes would be too much which resulted in an error - Fixed a bug where an error would occur if the friendly wizard's shop would display a highest rarity item - Fixed an issue where pressing Escape in the main menu screen would generate an error - Fixed the naming of the items to be more consistent with the previous items (Uppercase consistency) - Fixed a bug where the damage calculations of Damage releaser was incorrect. - Fixed a bug which introduced some minor number inconsistencies in the post game screen - Buffed Overpowered mace 375% -> 425% - Buffed Damage releaser 600% -> 750% - Nerfed Head hunter 400% -> 375%
