Sort of like goldfishing MtG against an opponent who randomly blows up your stuff. You can design your own deck or use a precon

I thought this was an ICD at first. It's actually it's own game! Did you make this?

The instructions should start with an overview of the flavour and objectives. A monster is attacking, and you are trying to stop it. You are... a giant robot I guess? Or maybe the military, but you control the giant robot in addition to ordering people around? You get card each turn that cost resources, the monster attacks at random, etc... When you use up your deck I assume it's reshuffled? Just add a super succinct paragraph that sums up what I need to know first to the instructions.
I think the "Plant" tiles need to be renamed. "Plant" could mean a lot of things. Perhaps "reactor would be appropriate?
The church and statue don't do anything right? (Aside from drawing fire) If so it should state this outright in the description.
I got a big "RAmpage" thing. What's that mean? Figured it out.
A total city health stat would be helpful. Same with turrets/damage per turn.
I don't know what the "energy" stat does.

Obviously the graphics need work, but I'm going to assume that's already known. I don't mind the ASCII look but colour-coding would be helpful. The turret fire shouldn't be green, That looks like it heals the monster.

Yeah I made it. You're the second person to suggest adding a flavor overview to the rules, so I added that in as well as a description of the other tiles and the reshuffling

Great suggestion!
