Welp, I'm pretty sure I clicked everything that can be clicked, in various different orders, and I just couldn't make anything actually happen. Parts of the grid automatically filled up with little icons, and that was about it.
Some instructions on the game page would go a long way here - until then, I can't say I even played the game, so I can't really rate it. Which is a pity - I'm always down for some large robot action! Would love to give it another go with some guidance on what I'm actually supposed to be doing!
