A very nice game! Cool idea & art. Found a few bugs: when deploying & gathering many brain cells in one place the counter seems to be confused & gets wrong (e.g. I had 8 cells and after a lot of mouse clicks I only had 2). Also the cells sometimes sink into the ground (first pic), seems to happen when they are created too low so that they already intersect the ground upon creation. Managed to finish the game, though. Great job!
