This is very impressive. I love the look and feel of the game. I did have to go back and read the comments to see what I was missing as I kept dying at first and I didn't realise that I had to keep the walkers at the base to defend it. That may be my bad though. The game itself is really well designed and a lot of fun but I think it would benefit from a tutorial. It's a small thing though and something that can easily be implemented post-jam if you decide to continue with it (I hope you do). Excellent job!
