I personally believe a level editor would be AWESOME for this game, Especially if you could upload or share levels. Maybe levels are ranked by tier based on how many bots they have. It would be a ton of fun!
What I was thinking (just for example): Every bot has a certain amount of points attached to it based on how hard it is. The more points a level has total, the higher its tier.
(Still just for example):
< or = 500 points - Bronze Tier
501-1000 points - Silver Tier
1001-1500 points - Gold Tier
1501-2000 points - Diamond Tier
2001-2500 points - Titanium Tier
> 2500 points - Just... Don't Tier
Again just an idea, but thought I would share! :D
