Polyomignomes (working title)

+ tweaked rolling and merging slightly
- rolling is really hard to figure out when I merge shapes and I have no idea what to do

+ squares can now merge together
+ squares can now roll around

+ switched to unity's physics system as I am now changing my game to be a physics puzzle game
+ added a little ghost/sprite creature that follows your cursor
+ ghost changes colour depending on what it is touching
+ Camera now follows any posessed objects or the ghost
- forgot to post progress for a while
- procrastinating a lot

+ movement with satisfying, modifiable jumps coded in
+ collision working just fine
- need to work on movement changing based on the angle of the slope you are standing on
