Eh, good idea, but when the only challenge are the trees . . oh wait . . those annoying mines you can hardly see in the snow. Then hiding mines IN the trees . . dastardly :P
How has this got a 3.89 average? The AI of your bots is terrible . . they randomly switch targets when the original enemy has 1 or 2 hits left . . they purposely turn into walls if you don't manage to baby walk them around the arena every step . . extremely frustrating and tedious. A good concept, but instead of strategy, it just boils down to luck of what your bots decide to do this round. At least constructing bots in the shop was fun.
