I've been getting a lot of questions about this feature. It is something that I have been actively exploring since I started development.
I think it would be a lot of fun to add weapons and combat (what's a mecha without guns, right?), but so far the balance between combat and other gameplay elements hasn't been just right. This is why I didn't advertise it on the Kickstarter page - I don't want to promise something that isn't 100% perfect yet. It's definitely in the plans, though - the artwork is already drawn, just need to nail down the implementation.
Since I've received so many questions about this feature, I will prioritize work on it and post an update early next week. Thanks for the input everyone!
