Enemies now have a chance to drop gold pickups (100g each). To compensate, the game over screen no longer awards bonus gold for your level, and gives a bit less for depth, so total gold per run stays about the same.
Harder planets now have a gold multiplier
Added smooth shadows between blocks and the background
Most weapons got a small attack animation
"Weighted Vest" is replaced by "Golden Boots", with the same stats, but they can charge up a powerful jump so you can't get softlocked
The "Brownstone" biome on Klarsh is replaced by a mossy rock biome
Reapers now deal 2 damage, and later Reapers deal even more
Playing as the Police Car generates fewer blocks, to make driving easier
Small nerfs to Shopping List and Holy Spectrum
Headband now also gives attack duration per level
