Need some more on hazards, for example the diamonds and spiders came out of no where and so can't accurately plan. The enemies on the grid I feel need to have some way to appropiately plan around without trial and error.maybe like the farmer will only come towards you if it can see you or something along those lines. Apart from that a really good concept and apreciate the pause ability in the controls. May I suggest looking at the board game Robo Rally for some more ideas, that game has a very similar movement idea,
