I just tought up of a great twist for that Bot battle thing.
Instead of always making a new bot in the place of the loser bot, you add and/or remove stuff from it so that it will win.
You can add/remove a total of 6 pieces on your turn. Up to a max of 50 pieces/bot.
You can move things around on your bot as much as you want.
You must build on your side of the blue line.
Do not modify or attach to the opposing bot.
No attaching to the blue line or the red balls, I made them fall off screen on purpose.
You must make the opponent bot fall off screen on their side.
Here is the start, I made 2 almost identical bots with 3 pieces, the other one is just slighly longer.http://FantasticContraption.com/?designId=9101930
So what you do now is evolve the rightside bot since it falls off.
Tell me if I missed something important.
Let the battle begin :D
