Tower defense

Spoiler

I liked the concept, but will not be rating it due to some instabilities. I found the first part's timing too tight, especially since the crane often gets stuck if you move it too far away. The bots often stopped by bumping each other, forcing me to restart. It seems that I'm supposed to let the flying zapper bot in front survive to prevent that.

I was also able to win without B, although my solution would be hard to reproduce. I wasn't really able to see what happened, but I think that one of the bots triggered the win. But good job for one of your first levels. I really liked the architecture!
