 # Resolved #
 
 * Cannot fit into single-tile width pit
   Cause: Player/NPC looks slim enough to fit, but don't fit in the game
-  Solution: Draw them wider, allow them to fit into the pit (Phys resolver will glitch?)
-  __Solved__ — Player/NPC hitbox now have a width of 15 pixels.
+  Solution: Player/NPC hitbox now have a width of 15 pixels.

+* Actor stick to wall and not get off
+  Cause: Unknown
+  Solution: Changed collision detection method to CCD (continuous collision detection)
+
+* Actor with mass <2 behaves erratically
+  Details: Velocity becomes NaN when jumped
+  Cause: Floating-point precision error?
+  Solution: Changed every physics variable that uses Float to Double
