Serious Feature Bloat
Pets, multiple save slots, achievements, redesigned controls (with partial controller support), new music, updated graphics, wonderful new beam mechanics, bulk vendor options, new NPC behaviors, new item mutators, and more.
Access unique loot... with Flax! Flax can only be obtained via Loot Codes, which will drop from time to time on Twitter, Steam, and elsewhere.
Loot Codes expire quickly -- if you see one, hop in the game and claim it!
What else to expect?
