Update v1.3b:
Added Depth of Field toggle button in video menu (option doesn't save yet after closing the game)
Lowers sword cooldown of old savegames to new default value (from 1s to 0.125s)
Added 2 more sword damage upgrades (one in Red Town shop, one in a new chest hidden nearby)
Added 5 more coins in Red Town
Fixed shot buttons being magnetic; can't float them up anymore now

Update v1.3:
Major change on how the sword works: can now swing it much faster but can't keep button held anymore and it does by default only 2 damage. Replaced swing speed upgrades with damage increasing ones. Damage upgrades reduced values. This should make early game fighting a lot cooler

Added failsafe that chests can't kick you through the ground while opening them
