Nice work mate. I am just finishing up CodeMonkeys course too(Loved it).
I would agree with what Satinel said, you very quickly understand the enemy behaviour and there is nothing to discourage "cheese", The actual combat however to me felt quite good during any given engagement, maybe the big melee guy was a little OP and the healing effect seemed a little weak I would probably boost its effect and limit its use somehow.
looking at bumping the heal up but implementing some options to prevent using it to often also going to have a look at implementing the a* path finding to make the combat nicer. Really enjoyed the project will definitely run through it again from scratch and try some different things now I’ve learned more. Thanks for the feedback it’s most appreciated.
