Reworked weapons and companions. There are now only 12 different base weapons (6 melee, 6 ranged) and 6 different base companions. You need now to choose between 2 upgrade options each level up which also changes the appearance. Each object has different upgrade variants, some of them unique. Example: the sniper weapon (picture above) can only become an elemental ranged weapon that deals light damage.
Reworked UI. Made it more fun looking and easier to understand.
Reworked light and void mechanics. Damage is now instant and weapons focus enemies with highest / lowest hp.
Cards don't drop anymore and spawn every 10 sec instead. You also start with a full set of cards based on the selection in the main menu.
