Nice submission, love games like this!
I feel like I got pretty far and I noticed some things:
- I couldn't play a flamethrower (cost 4) when I had 3 money and the "Sale" effect.
- Somehow I could Take and Discard more than 1 card each turn
- The Ammo Effect was probably what got me that far. As I understand it it's just +2 money, right?
I enjoyed the gameplay, good job!
