On level 10 i put the robot dude under the water tank, started the electricity and turned it off when i got to the edge. Now i can't put anything under the tank...
Yes, a select all thing would be nice, maybe something like, if you've ever played Starcraft, the click-and-drag sorta thing. It was what i was expecting when i first started playing this game. I hope you continue making games like this. Another thing, in level 13 my base fell off of the map and i couldn't see myself... I'm sure you can fix it though.
