I love the idea! collect the dirty shopkeepers! It felt like it was a bit inspired by Zombie Tsunami?
Anyways I like the mechanics, I am sure you have faced some challenges with regards to camera lerping and the coins AI, but overall great job!
As a small piece of feedback it would have been useful to know clearly how many coins you need to take down a shopkeeper.
If you can find the time, would you please check out our game as well?!
Our twist of the theme is that a critic tries to play your unfinished game, and you fight from inside the computer to make him like it.
