Game of Squids C64

Hello - this is my first Commodore 64 game written in assembly language. The game isn't very good (or complete) and I've uploaded more as a way of tracking my journey. 

You play as Kinver. A young squid who's lost his family. the only way home is to collect four red hearts, whilst avoiding other enemy squids and  the fabled "grey heart".  You can fool other squids by matching their colour.
